Note: This register must always be accessed in halfwords.
The TIO0-9 Count Enable Register controls operation of TIO counters. To enable the counter in
software, enable the relevant TIO0-9 Enable Protect Register for write and set the count enable
bit by writing a 1. To stop the counter, enable the TIO0-9 Enable Protect Register for write and
reset the count enable bit by writing a 0.
In all but continuous mode, when the counter stops due to an occurrence of underflow, the
count enable bit is automatically reset to 0. Therefore, what you get by reading the TIO0-9
Count Enable Register is the status that indicates the counter's operating status (active or idle).
