Real-Time Clock Minutes Register
This register contains the current minutes count. The value in the RTC_MIN 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). Access to this register is Read Only if the RTC is locked and
Read/Write if the RTC is unlocked. See Table 81.
