The Output Compare Registers contain a 16-bit value that is continuously compared
with the counter value (TCNT5). A match can be used to generate an Output Compare
interrupt. The Output Compare Registers are 16-bit in size. To ensure that both the high
and low bytes are written simultaneously when the CPU writes to these registers, the
access is performed using an 8-bit temporary High Byte Register (TEMP). This
temporary register is shared by all the other 16-bit registers. See section "Accessing 16-
bit Registers" for details.
