end signal for

EXIRQ7 to EXIRQ0 input.

EXMSTP

Output External expansion module stop: Module stop signal for

external modules.

DMA controller

(DMAC)

DREQ1,

DREQ0

Input

DMA request 1 and 0: These pins request DMAC activation.

TEND1,

TEND0

Output DMA transfer end 1 and 0: These pins indicate the end of

DMAC data transfer.

16-bit timer-

pulse unit (TPU)

TCLKD to

TCLKA

Input

Clock input D to A: These pins input an external clock.

TIOCA0,

TIOCB0,

TIOCC0,

TIOCD0

I/O

Input capture/output compare match A0 to D0: The TGR0A

to TGR0D input capture input or output compare output, or

PWM output pins.

TIOCA1,

TIOCB1

I/O

Input capture/output compare match A1 and B1: The

TGR1A and TGR1B input capture input or output compare

output, or PWM output pins.

TIOCA2,

TIOCB2

I/O

Input capture/output compare match A2 and B2: The

TGR2A and TGR2B input capture input or output compare

output, or PWM output pins.

Serial

communication

interface (SCI)

TxD2,

TxD1,

TxD0

Output Transmit data: Data output pins.

RxD2,

RxD1,

RxD0

Input

Receive data: Data input pins.

SCK2,

SCK1

SCK0

I/O

Serial clock: Clock I/O pins.

D/A converter

DA0

Output Analog output: D/A converter analog output pins.

AVCC

Input

Analog power supply: This is the power supply pin for the

D/A converter. When the D/A converter is not used, this pin

should be connected to the system power supply (VCC).

AVSS

Input

Analog ground: This is the ground pin for the D/A converter.

This pin should be connected to the system power supply

(0 V).

Vref

Input

Analog reference power supply: This is the reference

voltage input pin for the D/A converter. When the D/A

converter is not used, this pin should be connected to the

system power supply (VCC).
