WRITE #A0H // set EEPROM operating mode → reading ; read data from EEPROM to
CV4~CV1 register
DELAY <10 µS // wait <10 µS to finish reading
WRITE #ACH // set EEPROM mode → reserve (finish reading data from EEPROM to
CV4~CV1 register)
„ Read
WRITE #F5H // set RE FLAG 101 → INSTRUCTION Bank 5
WRITE #D1H // EXTENSION COMMAND
WRITE #A0H // set EEPROM operating mode → reading
DELAY >10 µS // wait <10 µs to finish reading
WRITE #ACH // set EEPROM mode → reserve (finish reading)
WRITE #D0H // EXTENSION COMMAND
WRITE #A0H // set EEPROM operating mode → reading ; read data from EEPROM to
CV4~CV1 register.
DELAY >10 µS // wait <10 µs to finish reading
WRITE #ACH // set EEPROM mode → reserve (finish reading)
„ Erase
WRITE #F5H // set RE FLAG 101 → INSTRUCTION Bank 5
WRITE #A8H // set EEPROM operating mode → erasing ; erase EEPROM data to 1
DELAY 10*N MS // wait 10*N ms to finish erasing
WRITE #ACH // set EEPROM mode → reserve (finish erasing)
WRITE #F0H // set RE FLAG 000 → INSTRUCTION Bank 0
WRITE #B1H // EM65571 reset
WRITE #F5H // set RE FLAG 101 → INSTRUCTION Bank 5
WRITE #A0H // set EEPROM operating mode → reading ; read data from EEPROM to
CV4~CV1 register
DELAY <10 µS // wait <10 µS to finish reading
WRITE #ACH // set EEPROM mode → reserve (finish reading data from EEPROM to
CV4~CV1 register)
(CV4~CV1 should be equal to 1111 after erasing)
