5.4.4
There are two capture registers that store the timer count value on a trigger condition from GPIO signals. The
timer trigger signals TMR1IA and TMR1IB for Timer 1, and TMR2IA and TMR2IB for Timer 2 are provided by ex-
ternal signals routed to the GPIO pins.
These timer trigger signals are synchronized to the main 12MHz clock, passed to an optional glitch filter, and
followed by an edge detection circuitry.
These functions are controlled by software with the register bits

All glitch filters consist of a flip-flop-driven, 4-bit shift register clocked with the main 12MHz clock.
