Real-Time Clock Month Register
This register contains the current month count. The RTC_MON register begins
counting at
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 reg-
ister is Read Only if the RTC is locked and Read/Write if the RTC is unlocked. See
