Dear Mr.Tony Mui,
Thanks for providing the information regarding the issue you have observed. As we understand, the left port is consistently assigned priority for semaphores 2 and 3 on power-up. We would like to understand the state of the control signals Chip Enable (CEL and CER) and Semaphore pin (SEML SEMR) for both the ports on powerup. We also need a few more clarifications regarding the setup to help us understand the cause for this issue.
Since this query is application specific we request you to initiate a technical support case on our website: www.cypress.com/support
Please do provide your E-mail address if you want us to create the case on your behalf.
Thanks & Regards,
