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 is a read-only bit and cannot be modified.
Status flag that indicates that a TCNT underflow has
occurred when channels 1, 2, 4, and 5 are set to phase
counting mode.
In channels 0 and 3, bit 5 is reserved. It is always read as
0 and cannot be modified.
[Setting condition]
When the TCNT value underflows (changes from H'0000
to H'FFFF)
[Clearing condition]
When a 0 is written to TCFU after reading TCFU = 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.)
