The TCA.PERL and TCA.PERH register pair represents the 16-bit value, TCA.PER. 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. For more details on reading and writing 16-bit registers, refer to Accessing 16-bit Registers.

Bits 15:8 – PER[15:8]: Periodic high byte

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

Bits 7:0 – PER[7:0]: Periodic low byte

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

20.5.16 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.

TCA.CMPn registers are updated with the buffer value from their corresponding CMPnBUF register when

an UPDATE condition occurs.

The TCA.CMPnL and TCA.CMPnH register pair represents the 16-bit value, TCA.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. For more details on reading and writing 16-bit registers, refer to Accessing 16-bit Registers.
