FAULT pin.

IOUT_OC_ERR

If this bit is set, do not map the current output open-circuit error flag to the FAULT pin.

0x0

R/W

VOUT_SC_ERR

If this bit is set, do not map the voltage output short-circuit error flag to the FAULT pin.

0x0

R/W

DCDC_DIE_TEMP_ERR

If this bit is set, do not map the dc-to-dc die temperature error flag to the FAULT pin.

0x0

R/W

MAIN_DIE_TEMP_ERR

If this bit is set, do not map the main die temperature error flag to the FAULT pin.

0x0

Two Stage Readback Select Register

Address: 0x13, Reset: 0x130000, Name: TWO_STAGE_READBACK_SELECT

This register selects the address of the register required for a two stage readback operation. The address of the register selected for

readback is stored in Bits[D4:D0].

FAULT_PIN_STATUS

The FAULT_PIN_STATUS bit reflects the inverted current status of the FAULT pin.

READBACK_MODE

These bits control the SPI readback mode.

0x0

R/W

0: two stage SPI readback mode (default).

01: autostatus readback mode: the status register contents are shifted out on SDO for

every SPI frame.

10: shared SYNC autostatus readback mode. This mode allows the use of a shared SYNC

line on multiple devices (distinguished using the hardware address pins). After each valid

write to a device, a flag is set. This mode behaves similar to the normal autostatus read-

back mode, except that the device does not output the status register contents on SDO

as SYNC goes low, unless the internal flag is set (that is, the previous SPI write is valid).

11: the status register contents and the previous SPI frame instruction are alternately

available on SDO.

[4:0]

READBACK_SELECT

Select readback address for a two stage readback.

0x0

R/W

0x00: NOP register (default).

0x01: DAC_INPUT register.

0x02: DAC_OUTPUT register.

0x03: CLEAR_CODE register.

0x04: USER_GAIN register.

0x05: USER_OFFSET register.

0x06: DAC_CONFIG register.

0x07: SW_LDAC register.

0x08: key register.

0x09: GP_CONFIG1 register.

0x0A: GP_CONFIG2 register.

0x0B: DCDC_CONFIG1 register.

0x0C: DCDC_CONFIG2 register.

0x0D: reserved (do not select this option).

0x0E: reserved (do not select this option).

0x0F: WDT_CONFIG register.

0x10: DIGITAL_DIAG_CONFIG register.

0x11: ADC_CONFIG register.

0x12: FAULT_PIN_CONFIG register.

0x13: TWO_STAGE_READBACK_SELECT register.

0x14: DIGITAL_DIAG_RESULTS register.

0x15: ANALOG_DIAG_RESULTS register.

0x16: status register.

0x17: CHIP_ID register.
