Hello,
the MPC5674 DSPI interface supports a timed serial bus interface downstream. With that it is possible to send (i think 64) bits instead of 16 bits ( 32 bits in command Frame and 32 bits in data Frame).
But i can´t find more information about the upstream in this mode. Only the sentence ....the upstream frame can be handled by software using any available serial input...
What does this sentence mean? Should i implement the sampeling via software? i think that needs a lot of MCU time and how will i get the rising and falling edge of the SCK.
Or it is possible to use the DSPI interface as input?
Thank you for your response
This sentence means there is no dedicated hardware support for TSB Upstream channel and this is supposed to be implemented software way with eSCI module.
