* Does not matter if set as undervoltage or overvoltage.
Configuration Lock
Lock the configuration register bank and configuration
EEPROM contents after initial programming by setting
the lock bit high (see Table 10). Locking the configura-
tion prevents write operations to configuration EEPROM
and configuration registers except the configuration
lock bit. Set the lock bit to 0 to reconfigure the device.
Write Disable
A unique write disable feature protects the
MAX6884/MAX6885 from inadvertent user EEPROM
writes. As input voltages that power the serial interface,
a μP, or any other writing devices fall, unintentional
data may be written onto the data bus. The user
EEPROM write-disable function (see Table 11) ensures
that unintentional data does not corrupt the MAX6884/
MAX6885 user EEPROM data.
