When Timer1 Gate Toggle mode is enabled, it is
possible to measure the full cycle length of a Timer1
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

Preliminary
The T1GVAL bit (T1GCON<2>) indicates when the
Toggled mode is active and the timer is counting.
The Timer1 Gate Toggle mode is enabled by setting the
T1GTM bit (T1GCON<5>). When T1GTM is cleared,
the flip-flop is cleared and held clear. This is necessary
in order to control which edge is measured.
