5. Mode
Timeout: you can perform frame synchronization according to the timeout

and the timeout must be greater than half of the clock cycle.
CS: it contains a chip select line (CS). You can perform frame

synchronization according to CS. Press Mode to select "CS" and enter the
CS mode. At this point, you can select CS signal line and CS polarity. The CS
signal line can be CH1-CH4 or D0-D15. The CS polarity can be "
(high level is valid, namely the instrument starts transmitting data when the
CS is high level) or "
starts transmitting data when the CS is low level).
6. Timeout
When there are only two lines, the decoder can find the right start frame
according to the timeout. The timeout must be greater than the maximum clock
pulse width and less than the idle time between frames. For the setting method,
please refer to the introduction in "Parameter Setting Method".
7. Edge Setting
Press Edge to set the instrument to sample MISO and MOSI on the rising edge
( ) or falling edge (
8. Polarity Setting
Press Polarity to set the polarity of the SDA data line to
(low level is 1).
9. Width Setting
Press Width to set the number of digits per frame of data and the setting range
is from 4 to 32.
10. Order
Press Order to select "LSB" or "MSB" and the default is MSB.
11. Display-related Setting

12. Event Table
The event table displays the decoded data, the corresponding line number and
time in table format. Press Evt.Table  EventTable to select "ON"
This operation is only available when MATH  Decode1 / Decode2 
Decode is set to "ON") to enter the event table interface.
Format: set "Data" display format in the event table to HEX, DEC or ASC.
Focus: press this key and turn
