Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Day of Week
This field is written with the day of the week in the encodings 0x0 to 0x6.
The application defines which days are assigned to each encoding.
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Year Value
The last two digits of the year are written in this field in hexadecimal.
For example, "12" would be programmed into this field for 2012.
Bits 22:16 correspond to hex values from 0x0 to 0x63 (0 to 99 years).
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Month
The month value is written in this field in hexadecimal.
Bits 11:8 correspond to hex values from 0x1 to 0xC (1 to 12 months).
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Day of Month
The day of the month value is written in this field in hexadecimal.
Bits 4:0 correspond to hex values from 0x1 to 1F (1 to 31 days). The
