We are using the MPC5748G chip as an SPI slave. What is the maximum speed? grateful

Hi,

let me copy here from the datasheet:

And something was already discussed here:

Problem description: We use the 5748G chip as a slave node to interact with 3A through SPI. When the communication rate is 1M, it can run stably. When the communication rate is 2M, unexpected bytes will be inserted into the SPI data sent by the MCU. Cause data analysis to fail.

Is this due to the wrong EB configuration mode? There is still a problem with the underlying MCAL driver. Looking forward to reply.
