There are 2 bits in R1 (GSC_CTRL_1) which act as a ''Write Protect'' for EEPROM regions: 396 * EEPROM_WP_ALL (R1 .3) will dissalow user i2c writes to all EEPROM regions (does not affect ''secure key'' erasure cases)397 * EEPROM_WP_BOARDINFO (R1 .4) will dissallow user i2c writes to the ''Board Info'' EEPROM region396 * EEPROM_WP_ALL (R15.0) will dissalow user i2c writes to all EEPROM regions (does not affect ''secure key'' erasure cases) 397 * EEPROM_WP_BOARDINFO (R15.1) will dissallow user i2c writes to the ''Board Info'' EEPROM region 398 398 399 399 === EEPROM Secure Key Example ===
