DESCRIPTION
1 = IN1 falls below primary undervoltage threshold.
1 = IN2 falls below primary undervoltage threshold.
1 = IN3 falls below primary undervoltage threshold.
1 = IN4 falls below primary undervoltage threshold.
1 = IN5 (MAX6870 only) falls below primary undervoltage threshold.
1 = IN6 (MAX6870 only) falls below primary undervoltage threshold.
Not used.
1 = IN1 falls below secondary undervoltage threshold or rises above secondary overvoltage threshold,
depending on the settings in register 0Ch (see Tables 2, 3, and 4).
1 = IN2 falls below secondary undervoltage threshold or rises above secondary overvoltage threshold,
depending on the settings in register 0Ch (see Tables 2, 3, and 4).
1 = IN3 falls below secondary undervoltage threshold or rises above secondary overvoltage threshold,
depending on the settings in register 0Ch (see Tables 2, 3, and 4).
1 = IN4 falls below secondary undervoltage threshold or rises above secondary overvoltage threshold,
depending on the settings in register 0Ch (see Tables 2, 3, and 4).
1 = IN5 (MAX6870 only) falls below secondary undervoltage threshold or rises above secondary
overvoltage threshold, depending on the settings in register 0Ch (see Tables 2, 3, and 4).
1 = IN6 (MAX6870 only) falls below secondary undervoltage threshold or rises above secondary
overvoltage threshold, depending on the settings in register 0Ch (see Tables 2, 3, and 4).
Not used.
1 = WDI1 asserted.
1 = WDI2 asserted.
1 = GPI1 asserted.
1 = GPI2 asserted.
1 = GPI3 asserted.
1 = GPI4 asserted.
1 = MR asserted.
Not used.
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 μP, 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.
