• Bit 0 – EERE: EEPROM Read Enable
The EEPROM Read Enable Signal – EERE – is the read strobe to the EEPROM. When the
correct address is set up in the EEAR Register, the EERE bit must be written to one to trigger
the EEPROM read. The EEPROM read access takes one instruction, and the requested data
is available immediately. When the EEPROM is read, the CPU is halted for four cycles before
the next instruction is executed. The user should poll the EEPE bit before starting the read
operation. If a write operation is in progress, it is neither possible to read the EEPROM, nor to
change the EEAR Register.
