20.4. Backup Regulator and RAM
The smaRTClock includes a backup supply regulator that keeps the smaRTClock peripheral fully func-
tional when V
which can range from 1 V to 5.25 V. Switchover logic automatically powers smaRTClock from the backup
supply when the voltage at V
The smaRTClock also includes 64 bytes of backup RAM. This memory can be read and written indirectly
using the RAMADDR and RAMDATA internal registers.
Internal Register Definition 20.8. RAMADDR: smaRTClock Backup RAM Address
Bits 7–0: ALARMn: smaRTClock Alarm Target.
Note: The LSB of ALARM0 is not used. The LSB of the 47-bit smaRTClock timer will be compared
Bit 7:
smaRTClock Addresses: ALARM0: 0x08; ALARM1: 0x09; ALARM2: 0x0A; ALARM3: 0x0B; ALARM4: 0x0C; ALARM5: 0x0D
Note: These registers are not SFRs. They can only be accessed indirectly through RTC0ADR and RTC0DAT.

Note: This register is not an SFR. It can only be accessed indirectly through RTC0ADR and RTC0DAT.
These 6 registers (ALARM5–ALARM0) are used to set an alarm event for the smaRTClock
timer. The smaRTClock alarm should be disabled (RTC0AEN=0) when updating these reg-
isters.
against ALARM0.1.
RAMADDR: smaRTClock Battery Backup RAM Address Bits
These bits select the smaRTClock Backup RAM byte that is targeted by RAMDATA. This
address auto-increments after each read or write of RAMDATA.
