Description of the ERROR Registers
The device has two 32-bit wide error registers. The following lists contain a description of the
individual bits of each register. Unless otherwise noted, a “1” indicates an error or warning
condition.
Bit Name Read/
Write Meaning
0 CRC_DEVDRV_FAIL ro A CRC error was detected in the internal
PLB-21 driver. Please contact your
distributor.
1 CRC_DEFAULT_FAIL ro A CRC error was detected in the default
values. A re-save of the values should
correct this.
2 CRC_CONFIG_FAIL ro A CRC error was detected in the internal
configuration values. Please contact your
distributor.
3 reserved ro reserved
4 CRC_FFWDCAL_FAIL ro Indicates that the feed forward calibration
of channel 1 is faulty.
5 CRC_ISOLLCAL_FAIL ro Indicates that the current setpoint
calibration of channel 0 is faulty.
6 TEMP_OVERSTEPPED ro The internal temperature was beyond safe
operating limits.
7 TEMP_WARNING ro The internal temperature is 5 °C before
shutdown.
8 TEMP_HYSTERESE ro Device is cooling down. Temperature
needs to drop below (maximum – 10 °C)
9 VCC_FAIL ro Internal supply voltage error.
10 FAIL_DEFAULTS ro The loading of the default failed. Normally
this is because of a pending CRC error.
11 I2C_EEPROM_FAIL ro Internal EEProm error. Please contact your
distributor.
12 I2C_DAC_FAIL ro Internal DAC error.
13 I2C_RD_FAIL ro Indicates an I²C read error.
14 I2C_WR_FAIL ro Indicates an I²C write error.
15 ENABLE_POWERON ro Indicates that the ENABLE signal was
given during start-up.
16 TEMP_SENSOR_FAIL ro A “1” indicates an error.
