EEPROM
To provide better accuracy for the touch-screen portion of the LCD
module, static calibration data has been programmed in bytes 8-15 of the
EEPROM. This data is shown in
Table 2–28 .
Table 2–29 shows the pinout of I2C Serial EEPROM with HSMC
connector.
Figure 2–17 shows the I2C Serial EEPROM schematic.
