The Connect button in Figure 10 helps to establish MiniProg3 or MiniProg4 or USB-to-I2C connection and
enable communication via HPI if the hardware is configured correctly as shown in Figure 1 and Figure 3 and is
ready to use.
When the MiniProg3 or MiniProg4 is connected to your PC, you can see that GUI detects it as below: Click
Refresh to update the current available USB-to-I2C connection list.
Figure 10 Available connection displayed in GUI
Click Connect. MiniProg3/MiniProg4 or USB-I2C connection status is reflected in the status bar.
Figure 11 Connection status
Click Start to initiate HPI communication between the GUI and the BCR device. The Status bar will update to
reflect the connected power adapter status. The GUI is now ready to communicate with the BCR device and
obtain more information about the connection (between the BCR device and power source PD controller).
Figure 12 Adapter attached and HPI Established
The third item in the Status bar also shows the result of the last HPI communication. When the EZ-PD™BCR HPI
Utility is initially launched, the default status is shown as “None”. When you use the EZ-PD™BCR HPI Utility to
retrieve information from the connected BCR device, the status of the last request will be updated accordingly
in the Status bar. The status could be one of the following:
•Success: HPI communication succeeded and BCR responded with the relevant response code
•No response: HPI communication succeeded but BCR did not respond
•Failure: HPI communication failed
Figure 13 Status bar for HPI communication
Note that there will be a delay of 3-seconds in the Status Bar on MiniProg3 disconnection depending on the
MiniProg3 polling speed.
If a failure is indicated, see Troubleshooting.

1. BCR power sink capabilities
This provides information on Sink PDOs of the BCR device. Click Read Sink PDOs to display the list of sink
PDOs with the following operations:
−Write ‘Read_SINK_PDO’ (See PD_CONTROL in the BCR HPI specification)
−Receive ‘Read PDO data’ response (See Response Codes in the BCR HPI specification)
−Read Sink PDOs from Data Memory (See Data Memory in the BCR HPI specification)

2. Power adapters power source capabilities
This part provides the information on Source PDO(s) of the power adapter. Click Read Source PDOs to
display the list of source PDOs. The following operations happen in the system:
−Write ‘Read Source PDOs obtained from port partner’ message (See PD_CONTROL in the BCR HPI
specification)
−Receive ‘Read PDO data’ response (See Response Codes in the BCR HPI specification)
−Read Source PDOs from Data Memory (See Data Memory in the BCR HPI specification)
3. BCR’s Sink PDOs Config
This part enables you to configure Sink PDOs. See Demo: BCR sink PDOs configuration.
2.5.2
The Adapter-PPS tab enables you to request the PPS output voltage and current value to the PPS source. The
PPS feature is supported only by the BCR-PLUS device in the BCR family. Unless you are connected to a BCR-
PLUS device, Adapter-PPS is automatically disabled.
Click the Read Source PDOs to show Power Adapter Power Source capabilities. If the power adapter supports
PPS, PPS capabilities are automatically loaded in PPS APDO List.
See Demo: PPS configuration for instructions.

The BCR device has a GPIO called “GPIO_1” that is assigned to Pin 8 of the BCR device; it is associated with pin 4
of J1 connector of the CY4533 EZ-PD™ BCR EVK board. It can be configured by the host processor to allow
control of some circuitry (i.e., LED control). The GPIO tab in the GUI demonstrates the different drive modes and
control options for that GPIO. Note that only the CYPD3177 BCR device provides GPIO feature. If you use
CYPD3176 or CYPD3178 device, the GPIO tab is automatically disabled.
You can also refer to the EZ- for details on GPIO_1.
Figure 16 GPIO tab Analog input
From GPIO1 Drive Mode, you can select the drive mode. See SET_GPIO_MODE in the BCR HPI specification.
When you select the Analog Input option, you can read the GPIO_1 voltage level. See SAMPLE_GPIO register in
the BCR HPI specification.
Once you select other digital drive modes, the GUI provides additional options to set and the logic status. See
READ_GPIO_LEVEL and SET_GPIO_LEVEL in the BCR HPI specification.

The BCR device supports the following two Sink PDOs by default. In Variable Sink PDO, the ‘Minimum Required
Voltage’, ‘Maximum Required Voltage’ and ‘Required Operating Current’ are determined by Pin 1 (VBUS_MIN),
Pin 2 (VBUS_MAX), Pin 5 (ISNK_COARSE), and Pin 6 (ISNK_FINE) using a resistor divider. See EZ-
datasheet.
•Fixed, 5 V, [Required operating current]
•Variable, [Minimum required voltage] ~ [Maximum required voltage], [Required operating current]
Change the Sink PDOs based on your system requirements. This section provides a simple example of how to
configure BCR Sink PDOs.
Note:
1. All settings for the power contracts are volatile. If power is recycled/removed, the contract goes back to default
values.
2. Instructions in Demo: BCR sink PDOs configuration use CY4533 EZ-PD™ BCR EVK using the CYPD3177 device.
3. The specific pin information is related to the CYPD3177 device only. The BCR-PLUS device has a different pin
map; see the BCR-PLUS datasheet.
2.6.1
To identify the Sink PDOs of the BCR device connected to the PC running the EZ-PD™BCR HPI Utility, click Read
Sink PDOs. The current Sink PDOs is shown in the ‘BCR Power Sink Capabilities’ table.

PDOs to the BCR device over HPI.
Click Read Sink PDOs to verify that the configuration is applied to the Sink PDOs.

If the power adapter supports the configured Sink PDOs, the PD contract will be re-negotiated based on the
configured Sink PDOs.
Note: If the rotary switch position of the CY4533 EZ-PD™ BCR EVK is modified, the user-configured Sink
PDOs are removed and restored back to the original Sink PDOs of the BCR device .
