T8 Enable
This field enables T8 when set (written) to 1.
Single/Modulo-N
When set to 0 (modulo-n), the counter reloads the initial value when the terminal
count is reached. When set to 1 (single pass), the counter stops when the terminal
count is reached.
Time-Out
This bit is set when T8 times out (terminal count reached). To reset this bit, a 1
must be written to this location.
