U-0 U-0 U-0 R/W-x R/W-x R/W-x R/W-x R/W-x
— — — MTHTEN0 MTHONE3 MTHONE2 MTHONE1 MTHONE0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-5 Unimplemented: Read as ‘0’
bit 4 MTHTEN0: Binary Coded Decimal Value of Month’s Tens Digit bit
Contains a value of 0 or 1.
bit 3-0 MTHONE<3:0>: Binary Coded Decimal Value of Month’s Ones Digit bits
Contains a value from 0 to 9.
Note 1: A write to this register is only allowed when RTCWREN = 1.
