Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
u = Bit is unchanged x = Bit is unknown -n/n = Value at POR and BOR/Value at all other Resets
‘1’ = Bit is set ‘0’ = Bit is cleared
bit 7-0
EEDAT<7:0>: Read/write value for EEPROM data byte or Least Significant bits of program memory
REGISTER 11-2: EEDATH: EEPROM DATA HIGH-BYTE REGISTER
