When Timer3 gate value status is utilized, it is possible
to read the most current level of the gate control value.
The value is stored in the T3GVAL bit (T3GCON<2>).
The T3GVAL bit is valid even when the Timer3 gate is
not enabled (TMR3GE bit is cleared).

When the Timer3 gate event interrupt is enabled, it is
possible to generate an interrupt upon the completion
of a gate event. When the falling edge of T3GVAL
occurs, the TMR3GIF flag bit in the PIR2 register will be
set. If the TMR3GIE bit in the PIE2 register is set, then
an interrupt will be recognized.
The TMR3GIF flag bit operates even when the Timer3
gate is not enabled (TMR3GE bit is cleared).
