Counter Up/Down Control
Specifies whether TCC functions as an up-
counter or down-counter, or whether
selection of counting up or down is controlled
by the input signal level on the UD pin.
00: TCC is an up-counter
01: TCC is a down-counter
1x: Selection through the signal level on the
UD pin
UD pin input high: Down-counter
UD pin input low: Up-counter

11.4.1 Interval Timer Operation 232 Modified
TCC up/down-count control can be specified by bits TMC6
and TMC5 in TMC, or selected by the input signal level on the
UD pin.
11.4.3 Event Counter Operation 233 Modified
Timer C can operate as an event counter, with the TMIC pin as
the event input pin. External event counting is selected by setting
bits TMC3 to TMC0 in the timer mode register C (TMC) to B'0111
or B'1111, and setting the TMIC bit in PMRE to 1. TCC counts
up/down at the rising/falling edge of an external event signal
input at the TMIC pin.
The external event input signal is not counted correctly if it does
not satisfy the high width or low width of the input pin.

the External Input Pin

243 Modified
OCRF contents are constantly compared with TCF, and when
both values satisfy the compare match condition, CMFH is set to
1 in TCSRF.
