Hi team,
The I2C data format requirements are as follows, I2C data sent by the host to the 8316 should be transmitted with the upper byte first followed by the lower byte as described:
The following figure shows the recommended configuration data in the MCF8316A tuning guide document:
The following is a screenshot of the configuration data sent to the 8316 by the host using the logic analyzer:
The data 0x44638c20 is configured first, with an endian conversion before sending, so that the data is transmitted with the upper byte and then the lower byte. The data is then configured, no endian conversion is performed, and the data is transmitted with the low byte and then the high byte. Is the correct data format to be endian and then transmitted?
Could you please help check this case? Thanks.
Best Regards,
Cherry
