14.8.3 TIMER1 GATE TOGGLE MODE

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 Figure 14-5.)

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.
