Timer pins
TMOW
10
12
Output
Clock output: This is an output pin for
waveforms generated by the timer A
output circuit.
AEVL
25
27
Input
Asynchronous event counter event
AEVH
24
26
input: This is an event input pin for input
to the asynchronous event counter.
TMIC
15
17
Input
Timer C event input: This is an event
input pin for input to the timer C counter.
UD
19
21
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
17
19
Input
Timer F event input: This is an event
input pin for input to the timer F counter.
TMOFL
11
13
Output
Timer FL output: This is an output pin
for waveforms generated by the timer FL
output compare function.
TMOFH
12
14
Output
Timer FH output: This is an output pin
for waveforms generated by the timer
FH output compare function.
TMIG
13
15
Input
Timer G capture input: This is an input
pin for timer G input capture.
