[3:1] SDO_DRDYB_ DRIVER
SDO/DRDYB Driver – sets who is driving the SDO/DRYB pin
Whenever CSB is
Asserted and the Device
is Reading ADC_DOUT
Whenever CSB is
Asserted and the Device
is Not Reading
ADC_DOUT
CSB is
Deasserted
0x0 (default)
SDO is driving
DRDYB is driving
High-Z
0x3
SDO is driving
DRDYB is driving
0x4
SDO is driving
High-Z
Others
Forbidden
0
SW_OFF_TRG
Switch-off trigger - refers to the switching of the output drive from the slave to the master.
0 (default):
SDO will be high-Z after the last (16th, 24th, 32nd, etc) rising edge of SCLK.
This option allows time for the slave to transfer control back to the master at the end of the
frame.
1:
SDO’s high-Z is postponed to the subsequent falling edge following the last (16th, 24th,
32nd, etc) rising edge of SCLK. This option provides additional hold time for the last bit, DB0,
in non-streaming read transfers.
SPI_STREAMCN: SPI Streaming Control
(Address 0x03)
Bit
Bit Symbol
Bit Description
7
STRM_TYPE
Stream type
0 (default):
Normal Streaming mode
1:
Controlled Streaming mode
[6:0] STRM_ RANGE
Stream range – selects Range for Controlled Streaming mode
Default:
0x00
DATA_ONLY_1: Data Only Read Control 1
(Address 0x09)

[6:0] DATA_ONLY_ADR
Start address for the Data Only Read Transaction
Default:
0x1A
Please refer to the description of DT_ONLY_SZ in DATA_ONLY_2 register.
