EEPROM Contents
The contents of EEPROM are primarily dependent on the specifications of the LCD
panel. SmartASIC provides suggested EEPROM contents for LCD panels from
various panel manufacturers. The section presents all the entries in the EEPROM, and
briefly describes their definitions. That allows the system manufacturers to have their
own EEPROM contents to distinguish their monitors.
The EEPROM contents can be partitioned into 11 parts. The first 8 parts are input
mode dependent. When the SD1200 detects the input mode, it will then load the
information related to the detected mode from the EEPROM. The information in the
9^th part is mainly for input mode detection as well as some threshold values for error
status indicators. The 10^th and 11^th parts are look up table for interpolation parameters.
The 9^th, 10^th and 11^th parts are loaded in the SD1200 during the reset time.
• Part 1: 640x350 mode,
