The MMCSM is a versatile counter submodule capable of performing complex counting and timing
functions, including modulus counting, in a wide range of applications. The MMCSM may also be
configured as an event counter, allowing the overflow flag to be set after a predefined number of events
(internal clocks or external events), or as a time source for other submodules.
The main components of the MMCSM are an 8-bit prescaler counter, an 8-bit prescaler register, a 16-bit
up-counter register, a 16-bit modulus latch register, counter loading and interrupt flag generation logic.
The contents of the modulus latch register is transferred to the counter under the following three
conditions:
Software can also write a value to the modulus register for later loading into the counter with one of the
two first criteria.
A software control register selects whether the clock input to the counter is one of the prescaler outputs or
the corresponding input signal. The polarity of the external input signal is also programmable.
The following sections describe the MMCSM in detail. A block diagram of the MMCSM is shown in

modulus register and immediately transferred to the counter.

The MMCSM can also operate as a free running counter by loading the
modulus value of zero.
