A successful channel 3 output compare overrides any channel 2:0 compares.
For each OC3M bit that is set, the output compare action reflects the
corresponding OC3D bit.

Reserved, should be cleared.
Output compare 3 mask. Setting an OC3M bit configures the corresponding PORTTn
pin to be an output. OC3Mn makes the GPT port pin an output regardless of the data
direction bit when the pin is configured for output compare (IOSx = 1). The OC3Mn
bits do not change the state of the PORTTnDDR bits. These bits are read anytime,
write anytime.

Reserved, should be cleared.
Output compare 3 data. When a successful channel 3 output compare occurs, these
bits transfer to the PORTTn data register if the corresponding OC3Mn bits are set.
These bits are read anytime, write anytime.
