CHAPTER 13 16-BIT I/O TIMER
13.4.3
16-bit Output Compare Operation
In the 16-bit output compare operation, an interrupt request flag can be set and the
output level can be reversed when the specified compare register value matches the 16-
bit free-run timer value. The CMOD0 and CMOD1 bits can be used to define the
corresponding compare registers for each pin.

every match with the register value. Each output value is controlled by one compare register.
OUT0: The level is only reversed by a match with compare register 0.
OUT1: The level is only reversed by a match with compare register 1.
