SLIPBIT_ERR

This bit flags an SPI frame slip bit error, that is, the MSB of the SPI word is not

equal to the inverse of MSB − 1.

SPI_CRC_ERR

This bit flags an SPI CRC error.

Analog Diagnostic Results Register

Address: 0x15, Reset: 0x150000, Name: ANALOG_DIAG_RESULTS

This register contains an error flag corresponding to the four voltage nodes (VLDO, INT_AVCC, REFIN, and REFOUT) monitored in

the background by comparators, as well as a flag for each die temperature, which is also monitored by comparators. Voltage output short

circuit, current output open circuit, VIOUT overvoltage, and dc-to-dc error flags are also contained in this register. Like the DIGITAL_

DIAG_RESULTS register, all of the flags contained in this register require a 1 to be written to them to update or clear them. When the

corresponding diagnostic features are not enabled, the respective error flags are read as zero.

R/W-1-C

DCDC_P_PWR_ERR

This bit flags a dc-to-dc regulation fault, that is, the dc-to-dc circuitry cannot reach

the target VDPC+ voltage due to an insufficient AVDD1 voltage.

0x0

R/W-1-C

VLDO_CAP_ERR

This bit flags an error if no capacitor present on VLDO pin following the capacitor

detect test.

0x0

R/W-1-C

IOUT_OC_ERR

This bit flags a current output open circuit error. This error bit is set in the case of a

current output open circuit and in the case where there is insufficient headroom

available to the internal current output driver circuitry to provide the programmed

output current.

0x0

R/W-1-C

VOUT_SC_ERR

This bit flags a voltage output short-circuit error.

0x0

R/W-1-C

DCDC_DIE_TEMP_ERR

This bit flags an overtemperature error for the dc-to-dc die.

0x0

R/W-1-C

MAIN_DIE_TEMP_ERR

This bit flags an overtemperature error for the main die.

0x0

R/W-1-C

REFOUT_ERR

This bit flags that the REFOUT node is outside of the comparator threshold levels

or if its short-circuit current limit occurs.

0x0

R/W-1-C

REFIN_ERR

This bit flags that the REFIN node is outside of the comparator threshold levels.

0x0

R/W-1-C

INT_AVCC_ERR

This bit flags that the INT_AVCC node is outside of the comparator threshold levels.

0x0

R/W-1-C

VLDO_ERR

This bit flags that the VLDO node is outside of the comparator threshold levels or if

its short-circuit current limit occurs.
