Description

15-14 SD_FLT

R/W

Self-Diagnostic Fault Action

These bits set the device action after a self-diagnostic fault.

0h = No Action

1h = Set DAC to CLEAR state

2h = Switch to alarm voltage determined by ALMV_POL (default)

3h = Place DAC into Hi-Z (power-down)

13-12 TEMP_FLT

R/W

TEMP Fault Action

These bits set the device action if the ADC temperature is outside the

TEMP_THRESHOLD Hi or Lo thresholds.

0h through 3h = Same as SD_FLT field (default 0h)

11-10 AIN1_FLT

R/W

AIN1 Fault Action

These bits set the device action if the ADC AIN1 channel is outside the

AIN1_THRESHOLD Hi or Lo thresholds.

0h through 3h = Same as SD_FLT field (default 0h)

9-8

AIN0_FLT

R/W

AIN0 Fault Action

These bits set the device action if the ADC AIN0 channel is outside the

AIN0_THRESHOLD Hi or Lo thresholds.

0h through 3h = Same as SD_FLT field (default 0h)

7-6

CRC_WDT_FLT

R/W

CRC and WDT Fault Action

These bits set the device action when a SPI CRC or SPI Watchdog Timeout error occurs.

0h through 3h = Same as SD_FLT field (default 0h)

5-4

VREF_FLT

R/W

VREF Fault Action

These bits set the device action when a fault is detected on VREF.

0h through 3h = Same as SD_FLT field a

3-2

THERM_ERR_FLT

R/W

Thermal Error Fault Action

These bits set the device action when a high temperature error occurs (> 130°C).

0h through 3h = Same as SD_FLT field (default 0h)

1-0

THERM_WARN_FLT R/W

Thermal Warning Fault Action

These bits set the device action when a high temperature warning occurs (> 85°C).

0h through 3h = Same as SD_FLT field (default 0h)
