4. Initial setting
4-1. EEPROM setting
Depending on that calibration is performed in either TSC-40/IC or host, you can select whether EEPROM
is used or not to store the correction data. EEPROM selection can be set via pin number 16, where
hardware reset release enables the setting.
4-2. Touch screen mode setting
Touch screen mode setting for 4-wire/5-wire is performed by setting pin number 15 to “H” or “L”. When
power supply is turned on, or hardware reset is released, pin number 15 is read to turn on in either
4-wire/5-wire mode.

4-3. Power supply voltage setting
Power supply mode setting for 3.3V/5V is performed by setting pin number 25 to “H” or “L”. When power
supply is turned on, or hardware reset is released, pin number 25 is read to turn on in either 3.3V mode/5V
mode.
