System Configuration
5.7.3.4
Each timer has a 16-bit field in GTCPR, used to latch the value of the counter when a defined transition of
TINx is sensed by the corresponding input capture edge detector.
5.7.4
This section provides an overview and detailed descriptions of the GTM signals.
There are four distinct external input timer capture signals (TIN1, TIN2, TIN3, and TIN4), four distinct
external input timer get signals (TGATE1, TGATE2, TGATE3, and TGATE4), and four distinct external
timer output signals (TOUT1, TOUT2, TOUT3, and TOUT4). The GTM interface signals are defined in

Normal gate mode enables the count on a falling edge of the TGATE pin and disables the count on
the rising edge of TGATE. This mode allows the timer to count conditionally, based on the state of
TGATE.
The restart gate mode performs the same function as normal mode, except it also resets the counter
on the falling edge of the TGATE pin. This mode has applications in pulse interval measurement
and bus monitoring.
