Bit Field

Field Name

Description

DAC resolution

7:5

DAC_RES[2:0]

On DAC161S997, returns a 111.

Returns the state of the ERRLVL pin:

4

ERRLVL_PIN

1 = ERRLVL pin is tied HIGH

0 = ERRLVL pin is tied LOW

Frame-error status sticky bit

1 = A frame error has occurred since the last STATUS read.

0 = No frame error occurred since the last STATUS read.

3

FERR_STS

This error is cleared by reading the STATUS register. A frame error is caused by an

incorrect number of clocks during a register write. A register write without an integer

multiple of 24 clock cycles will cause a Frame error.

SPI time out error

1 = The SPI interface has not received a valid command within the interval set by

SPI_TIMEOUT.

2

SPI_TIMEOUT_ERR

0 = The SPI interface has received a valid command within the interval set by

SPI_TIMEOUT

If this error occurs, it is cleared with a properly formatted write command to a valid

address.

Loop status sticky bit

1 = A loop error has occurred since last read of STATUS.

0 = No loop error has occurred since last read of STATUS.

1

LOOP_STS

Returns the loop error status. When the value in this register is 1, the DAC161S997 is

unable to maintain the output current set by DACCODE at some point since the last

STATUS read. This indicator clears after reading the STATUS register.

Current loop status

1 = A loop error is occurring.

0

CURR_LOOP_STS

0 = No loop error is occurring.

Returns the current Loop error status. When the value in this register is 1, the

DAC161S997 is unable to maintain the output current set by DACCODE.
