Part Number: CC3351
Other Parts Discussed in Thread: CC3350

Tool/software:

Hello expert,

In CC3350/3351 Datasheet of 6.19.2.1, it described SPI timing is different by SPH = 0 or 1 / SPO = 0 or 1.

How user can change this parameter SPH / SPO?

Regards,

    Fujinaka-San,

    The CC335x is a SPI peripheral device only, so there is no way from the CC335x side to change these parameters. Only the controller device, in this case the host processor, controls these lines. SPH/SPO are only relevant to the host. 

    The CC335x driver which is running on the host automatically controls the SPI lines and configures them accordingly, so there is no need to change anything here. 

    Regards,
