The
Dual Clock Comparator (MCU_DCC)
module, used
to determine the accuracy of a clock signal during the time execution of an application,
each having the following main features:
Two independent counter blocks
count clock pulses from each clock source
Each counter block is programmable,
however, for proper operation the counters must be programmed with seed values that
respect the ratio of the two clock frequencies
Configurable time base for error
signal
Error signal generation when one of
the clocks is out of spec
