-n = Value at POR
W = Writable bit
‘1’ = Bit is set
U = Unimplemented bit, read as ‘0’
‘0’ = Bit is cleared
x = Bit is unknown
bit 15-8
bit 7-4
bit 3-0
Unimplemented: Read as ‘0’
YRTEN<3:0>: Binary Coded Decimal Value of Year’s Tens Digit bits
Contains a value from 0 to 9.
YRONE<3:0>: Binary Coded Decimal Value of Year’s Ones Digit bits
Contains a value from 0 to 9.
Note 1: A write to the YEAR register is only allowed when RTCWREN = 1.
