Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Each bit in R34 enables or masks the
corresponding bit in R26. The default
value for these bits is 0 (unmasked).
RTC periodic interrupt.

Interrupt mask.
0 = Do not mask interrupt.
1 = Mask interrupt.
Each bit in R33 enables or masks the
corresponding bit in R25. The default
value for these bits is 0 (unmasked).
