MAX6884/MAX6885
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 P, 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.
