Real-Time Clock Alarm Minutes Register
This register contains the alarm minutes value. The value in the RTC_AMIN regis-
ter is unchanged by a RESET. The current setting of BCD_EN determines
whether the values in this register are binary (BCD_EN = 0) or binary-coded deci-
mal (BCD_EN = 1). See Table 89.
