EEPGD: Program/Data EEPROM Select bit
1 = Accesses program memory
0 = Accesses data memory
Unimplemented: Read as ‘0’
WRERR: EEPROM Error Flag bit
1 = A write operation is prematurely terminated (any MCLR Reset, any WDT Reset during
0 = The write operation completed
WREN: EEPROM Write Enable bit
1 = Allows write cycles
0 = Inhibits write to the data EEPROM
WR: Write Control bit
1 = Initiates a write cycle (The bit is cleared by hardware once write is complete. The WR bit can only
0 = Write cycle to the data EEPROM is complete
RD: Read Control bit
