Description
Count Direction Flag
Status flag that shows the direction in which TCNT counts in
channels 1, 2, 3, and 4.
In channel 0, bit 7 is reserved. It is always read as 1, and
should only be written with 1.
0: TCNT counts down
1: TCNT counts up
Reserved
This bit is always read as 1, and should only be written with
1.
Underflow Flag
Status flag that indicates that TCNT underflow has occurred
when channels 1 and 2 are set to phase counting mode.
Only 0 can be written, for flag clearing.
In channels 0, 3, and 4, bit 5 is reserved. It is always read
as 0, and should only be written with 0.

Overflow Flag
Status flag that indicates that TCNT overflow has occurred.
Only 0 can be written, for flag clearing.

•
When the TCNT value underflows (changes from H'0000
to H'FFFF)
When 0 is written to TCFU after reading TCFU = 1
When the TCNT value overflows (changes from H'FFFF
to H’0000)
In channel 4, when TCNT-4 is underflowed (H'0001 →
H'0000) in complementary PWM mode.
When 0 is written to TCFV after reading TCFV = 1
In channel 4, when DTC is activated by the TCIV
interrupt and the DISEL bit in DTMR of DTC is 0.
