Description
Status flag that shows the direction in which TCNT
counts in channels 1 to 4.
In channel 0, bit 7 is reserved. It is always read as 1
and the write value should always be 1.
0: TCNT counts down
1: TCNT counts up
Reserved
This bit is always read as 1. The write value should
always be 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 the write value should always be 0.
