Description
and CNT0, at a displacement of MOD60ALM increments past a modulo 60 boundary. Cleared by
writing 1 to this bit.
0 A MOD60ALMINT interrupt event has not occurred since this bit was last cleared by the CPU.
1 A MOD60ALMINT interrupt event has occurred since this bit was last cleared by the CPU.
Alarm Interrupt Source. ALMINT is a sticky flag that is the source of an optionally enabled interrupt
to the CPU. ALMINT indicates that an alarm event has occurred due to a match between the WUT
count and alarm register values. A match is defined as the value in CNT1, CNT0, and CNT2,
equating to the alarm time given by ALM1, ALM0, and ALM2. The detection of such an event is
enabled by ALMEN in CR0. ALMINT is cleared by writing 1 to this bit.
0 An ALMINT interrupt event has not occurred since this bit was last cleared by the CPU.
1 An ALMINT interrupt event has occurred since this bit was last cleared by the CPU.

Description
Reserved.
Pending Status of Posted Writes to the ALM1 Register. WPNDALM1 indicates if a posted register
write to ALM1 is currently pending.
0 The WUT can accept a new posted write to the ALM1 MMR.
1 A previously posted write to ALM1 is still awaiting execution. No new posting to this MMR can be
accepted.
Pending Status of Posted Writes to the ALM0 Register. WPNDALM0 indicates if a posted register
write to ALM0 is currently pending.
0 The WUT can accept a new posted write to the ALM0 MMR.
1 A previously posted write to ALM0 is still awaiting execution. No new posting to this MMR can be
accepted.
Pending Status of Posted Writes to the CNT1 Register. WPNDCNT1 indicates if a posted register
write to CNT1 is currently pending.
0 The WUT can accept a new posted write to the CNT1 MMR.
1 A previously posted write to CNT1 is still awaiting execution. No new posting to this MMR can be
accepted.
Pending Status of Posted Writes to the CNT0 Register. WPNDCNT0 indicates if a posted register
write to CNT0 is currently pending.
0 The WUT can accept a new posted write to the CNT0 MMR.
1 A previously posted write to CNT0 is still awaiting execution. No new posting to this MMR can be
accepted.
Pending Status of Posted Clearances of Interrupt Sources in the SR0 Register. WPNDSR0 indicates
if posted clearances of interrupt sources in SR0 are currently pending. Clearances can always be
accepted and accumulated into the same pending transaction for SR0. As such, accumulation is
nondestructive of previously posted clearances. This is in contrast to other MMRs, where posted write
data (rather than posted clearances) cannot be aggregated into one transaction.
0 The WUT can accept new posted clearances of interrupt sources in SR0 located in the 32 kHz
domain.
1 A previously posted clearance of interrupt sources in SR0 and maintained in the 32 kHz domain
is still awaiting execution. Additional clearances can still be aggregated into the existing, pending
transaction.
Pending Status of Posted Writes to CR0.
0 The WUT can accept a new posted write to CR0.
