15.5.4
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 Figure 15-4.)
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
Figure 15-5.)
