Description
0: SDIO is input only (4-wire SPI mode), and SDO is used for output.
1: SDIO is input/output (3-wire SPI mode), and SDO is unused.
0: SPI serial data byte is MSB first format.
1: SPI serial data byte is LSB first format.
1: software reset: SPI registers (except 0x00) to default values.
1: analog outputs temporarily disabled.
1: full device power-down; all circuits disabled except SPI.
1: power-down internal reference; use external reference source.
0: input data-word is twos complement binary format.
1: input data-word is unsigned binary format.
0: DDR mode.
1: SDR mode.
1: inverts the polarity of the data clock input.
1: inverts the polarity of the data clock output.
1: disables the data clock output.
1: enables sync manual mode; disables automatic update.
1: forces manual sync update.
1: indicates that sync logic requires update.
2-bit SMEM contents and calibration status indicator.
00: uncalibrated; SMEM contains default values (63).
01: self-calibrated; SMEM contains values from self-calibration.
10: factory-calibrated; SMEM values are transferred from FMEM.
11: user-calibrated; SMEM contains user-entered values.
3-bit self-calibration clock divider ratio. Affects time available for algorithm settling. Each
value increase reduces time by 50%.
000: self-calibration clock is DAC clock/4096 (maximum self-calibration settling time for
highest linearity accuracy).
001,010,011: self-calibration clock is DAC clock/2048,1024,512.
100,101,110: self-calibration clock is DAC clock/256,128,64.
111: self-calibration clock is DAC clock/32 (minimum self-calibration settling time for
fastest algorithm completion).
1: indicates completion of self-calibration cycle.
1: initiates self-calibration cycle.
1: indicates completion of memory transfer cycle.
1: initiates FMEM to SMEM transfer.
1: enables static memory (SMEM) write operation.
1: enable sstatic memory (SMEM) read operation.
1: enables factory memory (FMEM) read operation.
1: enables uncalibrated operation; all SMEM to default values.
