Counter Register - Normal Mode

The TCA.CNTL and TCA.CNTH register pair represents the 16-bit value, TCA.CNT. 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.

CPU and UPDI write access has priority over internal updates of the register.
