Description
Valid RAM and Time (Read Only). This bit senses the voltage that feeds the RTC
(VSB or VBAT) and indicates whether or not it was too low since the last time this bit
was read. If it was too low, the RTC contents (time/calendar registers and CMOS RAM)
is not valid. It is clear on V
0: The voltage that feeds the RTC was too low.
1: RTC contents (time/calendar registers and CMOS RAM) valid.
Reserved (Read Only). Reads as 0.
Description
Date of Month Alarm Data. Values may be 01 to 31 in BCD format or 01 to 1F in
binary format. When bits 7 and 6 are both set to one, an unconditional match is
