Description
R/(W)* Timer Overflow Flag
[Setting condition]
When TCNT_X overflows from H'FF to H'00
[Clearing condition]
Read OVF when OVF = 1, then write 0 in OVF
R/(W)* Input Capture Flag
[Setting condition]
When a rising edge and falling edge is detected in the
external reset signal in that order.
[Clearing condition]
Read ICF when ICF = 1, then write 0 in ICF
R/W Output Select 3, 2
R/W These bits specify how the TMOX pin output level is to
be changed by compare-match B of TCORB_X and
TCNT_X.
00: No change
01: 0 is output
10: 1 is output
11: Output is inverted (toggle output)
R/W Output Select 1, 0
R/W These bits specify how the TMOX pin output level is to
be changed by compare-match A of TCORA_X and
TCNT_X.
00: No change
01: 0 is output
10: 1 is output
11: Output is inverted (toggle output)
