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.
