Compare n Register - Normal Mode

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

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.

Bits 15:8 – CMP[15:8]: Compare High Byte

Compare High Byte

These bits hold the MSB of the 16-bit compare register.

Bits 7:0 – CMP[7:0]: Compare Low Byte

Compare Low Byte

These bits hold the LSB of the 16-bit compare register.
