Bit Bit Name
3 OS3
2 OS2
1 OS1
0 OS0
Notes: 1. Only 0 can be written to bits 7 to 5, to clear these flags.
2. Timer output is disabled when bits OS3 to OS0 are all 0. Timer output is 0 until the first
compare match occurs after resetting.

7 CMFB
Initial
Value R/W Description
0 R/W Output Select 3 and 2*
0 R/W These bits select a method of TMO pin output when
compare match B of TCORB and TCNT occurs.
00: No change when compare match B occurs
01: 0 is output when compare match B occurs
10: 1 is output when compare match B occurs
11: Output is inverted when compare match B occurs
0 R/W Output Select 1 and 0*
0 R/W These bits select a method of TMO pin output when
compare match A of TCORA and TCNT occurs.
00: No change when compare match A occurs
01: 0 is output when compare match A occurs
10: 1 is output when compare match A occurs
11: Output is inverted when compare match A occurs

When writing 0 after reading CMFB = 1
(When the CPU is used to clear this flag by writing 0
while the corresponding interrupt is enabled, be
sure to read the flag after writing 0 to it.)
When the DTC is activated by a CMIB interrupt
while the DISEL bit in MRB of the DTC is 0
