EEPGD: Program/Data EEPROM Select bit
1 = Accesses program memory
0 = Accesses data memory
Reads ‘0’ after a POR; this bit cannot be changed while a write operation is in progress.
Unimplemented: Read as ‘0’
WRERR: EEPROM Error Flag bit
1 = A write operation is prematurely terminated (any MCLR or any WDT Reset during normal
0 = The write operation completed
WREN: EEPROM Write Enable bit
1 = Allows write cycles
0 = Inhibits write to the EEPROM
WR: Write Control bit
1 = Initiates a write cycle. The bit is cleared by hardware once write is complete. The WR bit
0 = Write cycle to the EEPROM is complete
RD: Read Control bit
1 = Initiates an EEPROM read; RD is cleared in hardware. The RD bit can only be set (not
0 = Does not initiate an EEPROM read
