SB_EEPROM_DATA Bit Descriptions
Bit Name Description
31:8 RSVD Reserved.
7:0 EE_DATA EEPROM Data. This register holds the 8-bit data value to be written the EEPROM array
or the data most recently read from the array. Note that when reading a hidden location,
this register will return the previous read or write data with no indication of an error.
Writes to locked locations are ignored with no indication of an error.
