When T8 is enabled, the output T8_OUT switches to the initial value (CTR1, D1). If the
initial value (CTR1, D1) is 0, TC8L is loaded; otherwise, TC8H is loaded into the counter.
In SINGLE-PASS Mode (CTR0, D6), T8 counts down to 0 and stops, T8_OUT toggles,
the timeout status bit (CTR0, D5) is set, and a timeout interrupt can be generated if it is
enabled (CTR0, D1). In MODULO-N Mode, on reaching terminal count, T8_OUT is tog-
gled, but no interrupt is generated. From that point, T8 loads a new count (if the T8_OUT
level now is 0), TC8L is loaded; if it is 1, TC8H is loaded. T8 counts down to 0, toggles
T8_OUT, and sets the timeout status bit (CTR0, D5), thereby generating an interrupt if
enabled (CTR0, D1). One cycle is thus completed. T8 then loads from TC8H or TC8L
according to the T8_OUT level and repeats the cycle. See
You can modify the values in TC8H or TC8L at any time. The new values take effect
when they are loaded.

To ensure known operation do not write these registers at the time the values are to be
loaded into the counter/timer. An initial count of 1 is not allowed (a non-function
occurs). An initial count of 0 causes TC8 to count from 0 to
