Tec nical Summary
The 56F8013 Demonstration Board is designed as a versatile development card using the
56F8013 processor, allowing the creation of real-time software and hardware products to support
a new generation of applications in servo and motor control, digital and wireless messaging,
digital answering machines, feature phones, modems, and digital cameras. The power of the
16- it 56F8013 processor, com ined with the on- oard RS-232 interface and daughter card
connector, makes the 56F8013 Demonstration Board ideal for developing and implementing
many motor control algorithms, as well as for learning the architecture and instruction set of the
56F8013 processor.
The main features of the 56F8013 Demonstration Board, with oard and schematic reference
designators, include:
• 56F8013, a 16- it +3.3V digital signal controller operating at 60MHz [U1]
• Joint Test Action Group (JTAG) port interface connector, for an external de ug Host
Target Interface [J1]
• RS-232 interface, for easy connection to a host processor [U2 and P3]

2.2 RS-232 Serial Communications
The 56F8013 Demonstration Board provides an RS-232 interface y the use of an RS-232 level
converter, Sipex SP3220EUCY, designated as U2. Refer to the RS-232 schematic details in
Appendix A. The RS-232 level converter transitions the SCI port’s +3.3V signal levels to
RS-232-compati le signal levels and connects to the host’s serial port via connector P3. The SCI
ports signals, GPIOB6 and GPIOB7, can e disconnected from the RS-232 level converter y
cutting the JP1 and JP2 jumpers on the oard. The pin-out of connector P2 is shown in Table 2-1.

2.3 Debug LEDs
Six on- oard Light-Emitting Diodes, (LEDs), are provided to allow real-time de ugging for user
programs. These LEDs will allow the programmer to monitor program execution without having
to stop the program during de ugging; refer to Figure 2-1. Table 2-2 descri es the control of
each LED.
Setting GPIOA0, GPIOA1, GPIOA2, GPIOA3, GPIOA4, or GPIOA5 to a Logic One value will
turn on the associated LED.

2.4 Debug Support
A JTAG connector, J1, on the 56F8013 Demonstration Board allows the connection of an
external Host Target Interface for downloading programs and working with the 56F8013’s
registers. This connector is used to communicate with an external Host Target Interface, which
passes information and data ack and forth with a host processor running a de ugger program.
Table 2-3 shows the pin-out for this connector.
2.5 External Interrupts
Two on- oard push- utton switches are provided for external interrupt generation, as shown in
Figure 2-2. S1 allows the user to generate a hardware interrupt, IRQ #1, using GPIO Port B,
Bit 2. S2 allows the user to generate a hardware interrupt, IRQ #2, using GPIO Port B, Bit 3.
These two switches allow the user to generate interrupts for his user-specific programs.
Alternately, the user can use GPIO Port B, Bit 4 for IRQ #1. To accomplish this, cut the trace at
JP3 pins 1 and 2 and solder a jumper etween JP3 pins 2 and 3. Also, the user can use GPIO
Port B, Bit 5 for IRQ #2. To accomplish this, cut the trace at JP4 pins 1 and 2 and solder a jumper
etween JP4 pins 2 and 3.
