8.4 EEPROM Register Description
8.4.1 EEARH – EEPROM Address Register High Byte
8.4.2 EEARL – EEPROM Address Register Low Byte
8.4.3 EEDR – EEPROM Data Register
8266A-MCU Wireless-12/09
The EEPROM Address Registers EEARH and EEARL specify the EEPROM address in
the 4K bytes EEPROM space. The EEPROM data bytes are addressed linearly
between 0 and 4096. The initial value of EEAR is undefined. A proper value must be
written before the EEPROM may be accessed.
• Bit 7:4 – Res3:0 - Reserved
• Bit 3:0 – EEAR11:8 - EEPROM Address
The EEPROM Address Registers EEARH and EEARL specify the EEPROM address in
the 4K bytes EEPROM space. The EEPROM data bytes are addressed linearly
between 0 and 4096. The initial value of EEAR is undefined. A proper value must be
written before the EEPROM may be accessed.
• Bit 7:0 – EEAR7:0 - EEPROM Address
For the EEPROM write operation, the EEDR Register contains the data to be written to
the EEPROM in the address given by the EEAR Register. For the EEPROM read
operation, the EEDR contains the data read out from the EEPROM at the address given
by EEAR.
