CMPn

Compare n Register - Normal Mode

This register is continuously compared to the counter value. Normally, the outputs from the comparators are used to generate waveforms.

The TCAn.CMPn registers are updated with the buffer value from their corresponding TCAn.CMPnBUF register when an UPDATE condition occurs.

The TCAn.CMPnL and TCAn.CMPnH register pair represents the 16-bit value, TCAn.CMPn. The low byte [7:0] (suffix L) is accessible at the original offset. The high byte [15:8] (suffix H) can be accessed at offset + 0x01.
