With its maximum resolution of 2 system clock cycles, the GPT2 module provides
precise event control and time measurement. It includes two timers (T5, T6) and a
capture/reload register (CAPREL). Both timers can be clocked with an input clock which
is derived from the CPU clock via a programmable prescaler or with external signals. The
count direction (up/down) for each timer is programmable by software or may
additionally be altered dynamically by an external signal on a port pin (TxEUD)
Concatenation of the timers is supported via the output toggle latch (T6OTL) of timer T6,
which changes its state on each timer overflow/underflow.
The state of this latch may be used to clock timer T5, and/or it may be output on pin
T6OUT. The overflows/underflows of timer T6 can additionally be used to clock the
CAPCOM1/2 timers, and to cause a reload from the CAPREL register.
