Hi 

I need to change the inter-byte timing of a SPI data packet when sending from 8148 to device. Any advice on which register I should use? Thanks.

    Dan,

    I have checked the DM814x McSPI module registers, and I found just one time control register:

    MCSPI_CH(i)CONF[26:25] TCS

    This is programmable timing control between chip select and external clock generation. For more info see DM814x TRM, sections 22.3.12 McSPI Channel (i) Configuration Register (MCSPI_CH(i)CONF) and 22.2.3.8 Chip-Select Timing Control
