Operation of TCM modes
Each of the TCM in a PCA block supports four modes of operation. However, an exception is
when the TCM is configured in PWM Mode with programmable frequency. In this mode, all
TCM in a PCA block must be configured in the same mode or left to be not used.
Capture mode
The CAPCOM registers in the TCM are loaded with the counter values when an external pin
input changes state. The user can configure the counter value to be loaded by positive
edge, negative edge or any transition of the input signal. At loading, the TCM can generate
an interrupt if it is enabled.
Timer mode
The TCM modules can be configured as software timers by enable the comparator. The
user writes a value to the CAPCOM registers, which is then compared with the 16-bit
counter. If there is a match, an interrupt can be generated to CPU.
