22.3.2 RI Mask register (RIMASK - 0x400B 0004)
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
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.
Description
Compare register. Holds the compare value which is compared to the counter.
The Repetitive Interrupt Timer provides a versatile means of generating interrupts at
specified time intervals, without using a standard timer. It is intended for repeating
interrupts that aren’t related to Operating System interrupts. However, it could be used as
an alternative to the Cortex-M3 System Tick Timer
system requirements.

32-bit counter running from PCLK. Counter can be free-running, or be reset by a
generated interrupt.
32-bit compare value.
32-bit compare mask. An interrupt is generated when the counter value equals the
compare value, after masking. This allows for combinations not possible with a simple
compare.
