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.
