(1)
Bus Decoding
Refer
to RS232 Bus Decoding.
(2) Bit Width
Set the bit width of each frame of SPI protocol signal, which can set to 4～32.
(3) Bit Order
Specify whether the data bits of the SPI protocol signal to be decoded is high bit at the front (MSB) or
low bit at the front (LSB). MSB or LSB can be selected.
a.
MSB: The high bit of data is transmitted first.
b.
LSB: The low bit of data is transmitted first.
(4) CS Source
CS source can set any one of CH1～CH4 or D0-D15 to be chip selection input of SPI decoding signal. The
source supports display and select digital channel only when the digital channel is opened in LA.
(5) SCLK Source
Press SCLK source key to set any one of CH1～CH4 or D0-D15 to be clock source of SPI decoding signal.
The source supports display and select digital channel only when the digital channel is opened in LA.
(6) Data Source
Press MOSI source key to set any one of CH1～CH4 or D0-D15 to be data MOSI input of SPI decoding
signal. The source supports display and select digital channel only when the digital channel is opened in
LA.
