Timer pins
TMOW
14
Output
Clock output:
This is an output pin for
waveforms generated by the timer A output
circuit.
TMIC
19
Input
Timer C event input:
This is an event
input pin for input to the timer C counter.
UD
27
Input
Timer C up/down select:
This pin selects
up- or down-counting for the timer C
counter. The counter operates as a down-
counter when this pin is high, and as an up-
counter when low.
TMIF
21
Input
Timer F event input:
This is an event input
pin for input to the timer F counter.
TMOFL
15
Output
Timer FL output:
This is an output pin for
waveforms generated by the timer FL
output compare function.
TMOFH
16
Output
Timer FH output:
This is an output pin for
waveforms generated by the timer FH
output compare function.
TMIG
17
Input
Timer G capture input:
This is an input
pin for timer G input capture.
