15.5.2
The Timer3/5 gate source can be selected from one of
four different sources. Source selection is controlled by
the TxGSS<1:0> bits (TxGCON<1:0>). The polarity for
each available source is also selectable and is
controlled by the TxGPOL bit (TxGCON<6>).
TABLE 15-2:
15.5.2.1
The TxG pin is one source for Timer3/5 gate control. It
can be used to supply an external source to the gate
circuitry.

15.5.2.2
The TMR4/6 register will increment until it matches the
value in the PR4/6 register. On the very next increment
cycle, TMR4/6 will be reset to 00h. When this Reset
occurs, a low-to-high pulse will automatically be
generated and internally supplied to the Timer3/5 gate
circuitry.
15.5.3
When Timer3/5 Gate Toggle mode is enabled, it is
possible to measure the full cycle length of a Timer3/5
gate signal, as opposed to the duration of a single level
pulse.
The Timer1 gate source is routed through a flip-flop that
changes state on every incrementing edge of the
signal. (For timing details, see Figure 15-3.)
The TxGVAL bit will indicate when the Toggled mode is
active and the timer is counting.
Timer3/5 Gate Toggle mode is enabled by setting the
TxGTM bit (TxGCON<5>). When the TxGTM bit is
cleared, the flip-flop is cleared and held clear. This is
necessary in order to control which edge is measured.
