Register 7-1: EECON1 Register
bit 7
Unimplemented: Read as '0'
EEIF: EEPROM Write Operation Interrupt Flag bit
1 = The write operation completed (must be cleared in software)
0 = The write operation is not complete or has not been started
WRERR: EEPROM Error Flag bit
1 = A write operation is prematurely terminated
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.
0 = Write cycle to the data EEPROM is complete
RD: Read Control bit
1 = Initiates an EEPROM read. Read takes one cycle. RD is cleared in hardware.
0 = Does not initiate an EEPROM read
Legend
R = Readable bit
U = Unimplemented bit, read as ‘0’
Note 1: Future devices will have this bit in the PIR register.
U-0
The WR bit can only be set (not cleared) in software.
The RD bit can only be set (not cleared) in software.
