Real-Time Clock Minutes Register
This register contains the current minutes count. The value in the RTC_MIN register 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 decimal (BCD_EN = 1).
Access to this register is Read Only if the RTC is locked, and Read/Write if the RTC is
unlocked. See
Value
