Real-Time Clock Day-of-the-Week Register
This register contains the current day-of-the-week count. The RTC_DOW register
begins counting at
RESET. The current setting of BCD_EN determines whether the value in this reg-
ister is 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 Table 83.
