Note: • This register must always be accessed in halfwords
The TIO0–9 Count Enable Register controls operation of the TIO counters. To enable any TIO counter in
software, enable its corresponding enable protect bit for write and set the count enable bit by writing "1." To
stop any TIO counter, enable its corresponding enable protect bit for write and reset the count enable bit by
writing "0."
In all but continuous output mode, when the counter stops due to occurrence of an underflow, the count enable
bit is automatically reset to "0." Therefore, the TIO0–9 Count Enable Register when accessed for read serves
as a status register indicating whether the counter is operating or idle.
