Preliminary DS41393B-page 29 AR1000 SERIES RESISTIVE TOUCH SCREEN CONTROLLER 8.0 CONFIGURATION REGISTERS The Configuration registers allow application specific customization of the controller. The default values have been optimized for most applications and are automatically used, unless you choose to change them. Unique sensors and/or product applications may benefit from adjustment of Configuration registers. 8.1 Restoring Default Parameters • AR1010/AR1020 The factory default settings for the Configuration registers can be recovered by writing a value of 0xFF to address 0x00 of the EEPROM, then cycling power. • AR1011/AR1021 The factory default settings for the Configuration registers can be recovered by writing a value of 0xFF to addresses 0x01 and 0x29 of the EEPROM, then cycling power. Configuration registers are defined as an Offset value from the Start address for the register group. To read or write to a register, do the following: • Issue the REGISTER_START_ADDRESS_REQUEST com- mand to obtain the Start address for the register group. • Calculate the desired register’s absolute address by adding the register’s Offset value to Start address for the register group. • Issue the REGISTER_READ or REGISTER_WRITE command, using the calculated register’s absolute address. Note: Although most registers can be configured for a value ranging from 0 to 255, using a value outside the specified range for the specific register may negatively impact performance.
