Description
Count Direction Flag
Status flag that shows the direction in which TCNT
counts in channels 1, 2, 4, and 5.
In channels 0 and 3, bit 7 is reserved. It is always read
as 1 and cannot be modified.
0: TCNT counts down
1: TCNT counts up
Reserved
This bit is always read as 1 and cannot be modified.
Underflow Flag
Status flag that indicates that TCNT underflow has
occurred when channels 1, 2, 4, and 5 are set to
phase counting mode. Only 0 can be written, for flag
clearing.
In channels 0 and 3, bit 5 is reserved. It is always read
as 0 and cannot be modified.

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

[Clearing condition]
•
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 )
When 0 is written to TCFV after reading TCFV = 1
