4. MISO Setting

Press MISO to select any channel (CH1-CH4) as the MISO data channel. When

“OFF” is selected, this data line is not set.

5. MOSI Setting

Press MOSI to select any channel (CH1-CH4) as the MOSI data. When “OFF” is

selected, this data line is not set.

6. Edge Setting

Press Edge to sample the MISO and MOSI at the rising edge or falling edge of

CLK.

7. Polarity setting

Press Polarity to set the polarity of the SDA data line to (the high level is 1)

(the low level is 1).

8. Width Setting

Press Width to set the bit width of each frame. The range available is from 8 to

32.

9. Endian Setting

Press Endian to select “LSB” or “MSB” and the default is “MSB”.

10. Display-related Setting

 Press Format to set the display format of the bus to Hex, Decimal, Binary,

ASCII or LINE. Note that LINE format is displayed the acyual value of the

bus in a binary number form, and the order is consistent with the bus

transmission sequence. This format is only valid for the serial bus, because

the serial bus has the difference of bit sequence of LSB and MSB; if bit

sequence of the bus is selected MSB, the LINE format is the same to the

binary format.

 Press Pos and use to adjust the vertical display position of the bus.

11. Event Table

The event table displays the decoded data and the corresponding line number

and time in table form. It can be used to observe relatively longer decoded data

to solve the problem that some data cannot be viewed cleared on the screen.
