16.5.4
When Timer3/5/7 Gate Single Pulse mode is enabled,
it is possible to capture a single pulse gate event.
Timer3/5/7 Gate Single Pulse mode is first enabled by
setting the TxGSPM bit (TxGCON<4>). Next, the
TxGGO/TxDONE bit (TxGCON<3>) must be set.
The Timer3/5/7 will be fully enabled on the next incre-
menting edge. On the next trailing edge of the pulse,
the TxGGO/TxDONE bit will automatically be cleared.

No other gate events will be allowed to increment
Timer3/5/7 until the TxGGO/TxDONE bit is once again
set in software.
Clearing the TxGSPM bit also will clear the TxGGO/
TxDONE bit. (For timing details, see
Simultaneously enabling the Toggle mode and the
Single Pulse mode will permit both sections to work
together. This allows the cycle times on the Timer3/5/7
gate source to be measured. (For timing details, see
