Real-Time Clock Alarm Day-of-the-Week Register
This register contains the alarm day-of-the-week value. The value in the
RTC_ADOW register is unchanged by a RESET. The current setting of BCD_EN
determines whether the value in this register is binary (BCD_EN = 0) or binary-
coded decimal (BCD_EN = 1). See Table 91.
