EEADR
EECON1 and EECON2 Registers
The EEADR register can address up to a maximum of 256 bytes of data EEPROM.
The unused address bits are decoded. This means that these bits must always be '0' to ensure
that the address is in the Data EEPROM memory space.
EECON1 is the control register with five low order bits physically implemented. The upper-three
bits are unimplemented and read as '0's.
Control bits RD and WR initiate read and write, respectively. These bits cannot be cleared, only
set, in software. They are cleared in hardware at completion of the read or write operation. The
inability to clear the WR bit in software prevents the accidental, premature termination of a write
operation.
The WREN bit, when set, will allow a write operation. On power-up, the WREN bit is clear. The
WRERR bit is set when a write operation is interrupted by a MCLR reset or a WDT time-out reset
during normal operation. In these situations, following reset, the user can check the WRERR bit
and rewrite the location. The data and address will be unchanged in the EEDATA and
EEADR registers.
Interrupt flag bit EEIF is set when write is complete. It must be cleared in software.
EECON2 is not a physical register. Reading EECON2 will read all '0's. The EECON2 register is
used exclusively in the Data EEPROM write sequence.
