Block Diagram of GPT1
With its maximum resolution of 8 TCL, 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. The count direction (up/down) for each timer is programmable by software.
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. The overflows/underflows of timer
T6 can cause a reload from the CAPREL register. The CAPREL register may capture
the contents of timer T5 based on an external signal transition on the corresponding port
pin (CAPIN), and timer T5 may optionally be cleared after the capture procedure. This
allows the C161K/O to measure absolute time differences or to perform pulse
multiplication without software overhead.
