I/O

Name and Functions

Timer pins

IRQ0

Input

Timer B event counter input: This is

an event input pin for input to the timer B

counter.

IRQ1

Input

Timer C event counter input: This is

an event input pin for input to the timer C

counter.

Input

Timer C up/down select: This pin

selects whether the timer C counter is

used for up- or down-counting. At high

level it selects down-counting, and at low

level up-counting.

Input to this pin is valid only when bit

TMC6 in timer mode register C (TMC) is

set to 1.

EVENT

Input

Timer D event counter input: This is

an event input pin for input to the timer D

counter.

TMOE

Output Timer E output: This is an output pin for

waveforms generated by the timer E

output circuit.

14-bit PWM pin

PWM

Output 14-bit PWM output: This is an output

pin for waveforms generated by the

14-bit PWM.

SO1

Output Serial transmit data output (channels 1

SO2

and 2): These are SCI data output pins.

SI1

Input

Serial receive data input (channels 1

SI2

and 2): These are SCI data input pins.

SCK1

I/O

Serial clock I/O (channels 1 and 2):

SCK2

These are SCI clock I/O pins.

Output Chip select output: When SCI2 is in

transmit mode and the serial clock is an

internal clock, this pin goes low.

This function is valid when bit SI2 in port

mode register 2 (PMR2) is 1 and the CS

bit in PMR3 is 1.
