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.
(any MCLR reset or any WDT reset during normal operation)
