4.4.8. EEPROM Control Circuit
This printer has 2kbit EEPROM ( IC005 ). Page Count Data, Calibration Data, etc. are saved on the IC.
The EEPROM control signals are explained as follows.
EEPCS: This is the chip select signal.
EEPCLK: This is the serial data transfer clock.
EEPDO: This is the serial data from CPU ( IC004 ) to EEPROM ( IC005 ).
EEPDI: This is the serial data from EEPROM ( IC005 ) to CPU ( IC004 ).
