RES

Input

Reset: When this pin is driven low, the

chip is reset

RESO

Output

Reset output: Outputs the CPU

internal reset signal.

TEST

Output

Test pin: This pin is reserved and

cannot be used. It should be

connected to V

SS.

Interrupt

pins

IRQ

Input

IRQ interrupt request 0 to 4: These

are input pins for edge-sensitive

external interrupts, with a selection of

rising or falling edge.

WKP

7 to

WKP

50 to 43

53 to 46

Input

Wakeup interrupt request 0 to 7:

These are input pins for rising or

falling- edge-sensitive external

interrupts.

Timer pins TMOW

Output

Clock output: This is an output pin for

waveforms generated by the timer A

output circuit.

AEVL

AEVH

Input

Asynchronous event counter event

input: This is an event input pin for

input to the asynchronous event

counter.

TMIC

Input

Timer C event input: This is an event

input pin for input to the timer C

counter.

Input

Timer C up/down select: This pin

selects up- or down-counting for the

timer C counter. The counter operates

as an up-counter when this pin is high,

and as a down-counter when low.

TMIF

Input

Timer F event input: This is an event

input pin for input to the timer F

counter.

TMOFL

Output

Timer FL output: This is an output pin

for waveforms generated by the timer

FL output compare function.
