Description

RTC alarm B subsecond register

Fields

SS

Subseconds value
MASKSS

Mask the most-significant bits starting at this bit

0 (B_0x0): No comparison on subseconds for Alarm B. The alarm is set when the seconds unit is incremented (assuming that the rest of the fields match).

1 (B_0x1): SS[31:1] are don’t care in Alarm B comparison. Only SS[0] is compared.
SSCLR

Clear synchronous counter on alarm (Binary mode only)

0 (B_0x0): The synchronous binary counter (SS[31:0] in RTC_SSR) is free-running.

1 (B_0x1): The synchronous binary counter (SS[31:0] in RTC_SSR) is running from 0xFFFF FFFF to RTC_ALRBBINR.SS[31:0] value and is automatically reloaded with 0xFFFF FFFF one ck_apre cycle after reaching RTC_ALRBBINR.SS[31:0].
