Period Buffer Register

This register serves as the buffer for the period register (TCA.PER). Accessing this register using the CPU or UPDI will affect the PERBV flag.

The TCA.PERBUFL and TCA.PERBUFH register pair represents the 16-bit value, TCA.PERBUF. 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.
