2 STYLE AND FORMATTING CONVENTIONS
This chapter describes the formatting and styles used throughout this document.
2.1 Number Representation
Numbers other than decimal will have a postfix indicator. All numbers use little endian
formatting, with the most significant bit/digit to the left. Digits for binary and hexadecimal
representation are grouped with a single space every four digits to improve readability. Binary
numbers use “b” as a postfix and hexadecimal numbers use “h” as a postfix.
For example, 1011b binary = Bh hexadecimal = 11 decimal.
2.2 Formatting Styles
TYPE
EXAMPLE
DESCRIPTION
Register Name
RTCCTL
Register names use a capital letter and boldface type.
Register Bit(s)

register bit(s)
[RTCCTL.RTCCLKDIV]
Within text blocks, functions selected with a register bit setting are
set in brackets. For example [RTCCTL.RTCCLKDIV] means divider
settings /2 to /65536.

4 ANALOG REGISTER ACCESS
4.1 Overview
All analog registers in the PAC5526 are accessible through a SOC bus in the device. Unlike
registers in the MCU (SRAM and digital peripheral registers), these analog registers are not
memory mapped.
The block diagram below shows the different system busses that the MCU uses to access the
different system registers.

GPIO[A..G]
The PAC5526 contains two register buses: the AHB bus and the APB bus.
The AHB bus allows the MCU and Debug Port access to FLASH and SRAM via the Memory
Controller. To access other digital peripheral connected to the APB bus, there is a bridge from
the AHB to the APB bus so that the MCU or Debug Port can perform memory-mapped register
access to all digital peripherals. Some digital peripherals such as timers are flexibly connected
to IO using the DPM bus.
To access the Analog peripherals, the USARTA SPI peripheral is used to generate read and
write transactions to the Analog registers using the DPM and GPIOA.
4.2 Functional Description
External programming interfaces such as JTAG and SWD or the Arm®Cortex®-M4F MCU may
perform memory-mapped accesses to USART A through the AHB and APB busses on the
device.

Power Application Controller®
-16-Copyright 2020 © Qorvo, Inc.
Rev 1.0 –Jan 17, 2020
USART A is a serial communication peripheral that supports a SPI-like protocol that can be
used to communicate to the Analog Peripherals for read and write transactions. The Digital
Peripheral MUX (DPM) may be configured to connect the USART A SPI signals to GPIO A,
where they are connected to the Analog peripherals.
4.3 USART Configuration
USART A acts as a SPI bus master to communicate with the Analog Peripherals. The USART A
signals that are used for this communication are:
▪USASCLK –USART A SPI Clock
▪USAMOSI –USART A Master-Out/Slave-In
▪USAMISO –USART A Master-In/Slave-Out
▪USASS –USART A Slave Select
In order to communicate with the Analog Peripherals, the USART A should have the following
configuration:
▪8-bit mode
▪SCLK active high
▪CPH is sample/setup
▪SS active low
When communicating with the Analog Peripherals, the maximum SCLK frequency is 25MHz.
4.4 Protocol
The protocol for communicating with the Analog Peripherals is a simple two-byte protocol.
The first byte is always the address, which includes a 7-bit address [7:1] and a write bit [0]. For
write operations, the write bit [0] is set to 1b. For read operations, the write bit [0] is set to 0b.
For write operations, the 2nd byte will be the 8-bit data to write to the given address.
For read operations, the 2nd byte is ignored and MISO will contain the 8-bit data read from the
given address.
4.5 Write Register Example
To write the HPDAC register (address 2Bh) with the value 28h, issue the following transactions
to USART A:
▪Write SSPADAT with the value 57h (2Bh << 1 | 1b for write transaction)
▪Write SSPADAT with the value 28h
The timing diagram from a write operation is shown below.

4.6 Read Register Example
To read the contents of the HPDAC register, issue the following transactions to USART A:
▪Write SSPADAT with the value 56h (2Bh << 1 | 0b for read transaction)
▪Write SSPADAT with a dummy character
▪Read last data from MISO from SSPADAT, this is the register value
The timing diagram from a read operation is shown below.
Figure 4-3 Analog Peripheral Register Read Timing
For more information on how to configure the DPM to support the USART A peripheral for
communicating with the Analog Registers, see the PAC55XX Family User Guide.

5 PAC5526 IO
5.1 Overview
The Digital Peripheral MUX (DPM) on the PAC55XX family allows flexible assignment of
peripheral functions to IO pins.
Each member of the family has a different set of IO pins that are available. It is important during
application design that the designer consider the available IO pins to make sure the necessary
peripherals will be available.
Below is a diagram of the GPIO and MUX structure.
Figure 5-1 GPIO and DPM Block Diagram
Each IO can be configured to select 1 of up to 8 digital peripheral signals. Some IOs also may
be used as an ADC input. For information on how to configure the IO for each of these
situations, see the PAC55XX Family User Guide.
The PAC5526 has the following IO pins available for application use:
▪PA[7:0] –Reserved for MMPM, ASPD, CAFE
▪PB[7:0] –Reserved for ASPD
▪PD[7:4]
▪PE[3:0]
▪PF[7:0]
▪PG[6:3]
