Table 10. Jumper configuration of SPI chain
Function
Configuration of SPI daisy chain loop with two devices (HS+LS)
Suitable for:
• single board configuration with two device daisy chain.
See Section 4
• slave board closing the chain in multiple board
configuration. See Section 5
Configuration of SPI daisy chain loop with only one device (LS).
Suitable for single board configuration with only LS connected.
Configuration to leave open the SPI daisy chain loop and to
propagate SDO_H in multiple board configuration
Suitable in multiple board configuration for:
• the master board
• the middle slave board(s)
See Section 5
