C EEPROM Configuration (SW7)
Switch SW7 determines the I
2
C EEPROM configuration options. When a switch is in the ON position, its related
signal is deasserted to 0. When the switch is in the OFF position, its related signal is asserted to 1. The default
factory settings for the MSC711xADS board are 1–4 = ON.
• Switches 1–3 set the EEPROM I
2
C bus address.
• Switch 4 sets the write protection mode for the EEPROM.
