Description
Compare register
Mask register. This register holds the 32-bit mask value. A ‘1’
written to any bit will force a compare on the corresponding bit of
the counter and compare register.
Control register.
32-bit counter
Description
Compare register. Holds the compare value which is
compared to the counter.
Description
Mask register. This register holds the 32-bit mask value. A one written
to any bit overrides the result of the comparison for the corresponding
bit of the counter and compare register (causes the comparison of the
register bits to be always true).

Description
Interrupt flag
This bit is set to 1 by hardware whenever the counter value
equals the masked compare value specified by the contents
of RICOMPVAL and RIMASK registers.
Writing a 1 to this bit will clear it to 0. Writing a 0 has no
effect.
The counter value does not equal the masked compare
value.
Timer enable clear
The timer will be cleared to 0 whenever the counter value
equals the masked compare value specified by the contents
of RICOMPVAL and RIMASK registers. This will occur on
the same clock that sets the interrupt flag.
The timer will not be cleared to 0.
