MAX6870/MAX6871
and WDI_ bits assert if any of the GPI_ inputs are config-
ured as watchdog inputs (WDI_) and a watchdog fault
occurs.
Configuration Lock
Lock the configuration register bank and configuration
EEPROM contents after initial programming by setting
the lock bit high (see Table 30). Locking the configura-
tion prevents write operations to all registers except the
configuration lock register. Clear the lock bit to recon-
figure the device.
Write Disable
A unique write disable feature protects the MAX6870/
MAX6871 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 writ-
ten onto the data bus. The user EEPROM write disable
function (see Table 31) ensures that unintentional data
does not corrupt the MAX6870/MAX6871 EEPROM data.
