bit 2
bit 1
bit 0
EECON1 REGISTER (ADDRESS: 9Ch)
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
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. The RD bit
0 = Does not initiate an EEPROM read
bit 7
