• Bit 3 – EERIE: EEPROM Ready Interrupt Enable
Writing EERIE to one enables the EEPROM Ready Interrupt if the I-bit in SREG is set. Writing
EERIE to zero disables the interrupt. The EEPROM Ready Interrupt generates a constant
interrupt when Non-volatile memory is ready for programming.
• Bit 2 – EEMPE: EEPROM Master Program Enable
The EEMPE bit determines whether writing EEPE to one will have effect or not.
When EEMPE is set, setting EEPE within four clock cycles will program the EEPROM at the
selected address. If EEMPE is zero, setting EEPE will have no effect. When EEMPE has been
written to one by software, hardware clears the bit to zero after four clock cycles.
• Bit 1 – EEPE: EEPROM Program Enable
The EEPROM Program Enable Signal EEPE is the programming enable signal to the
EEPROM. When EEPE is written, the EEPROM will be programmed according to the EEPMn
bits setting. The EEMPE bit must be written to one before a logical one is written to EEPE, oth-
erwise no EEPROM write takes place. When the write access time has elapsed, the EEPE bit
is cleared by hardware. When EEPE has been set, the CPU is halted for two cycles before the
next instruction is executed.
• 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.
