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 and/or it may be output on pin
T6OUT. 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 C165 to measure
absolute time differences or to perform pulse multiplication without software overhead.
