i use a CY7C65215A for two serial port, one is RS485(TX enabled).
but I found that the TX enable signal has a large and not fixed delay after last bit send. ~200 - 800us!! it's too large!

Hello,
The time duration over which the EN pin is driven high is not fixed. It depends on the amount of data sent. The pin will not be driven for too long.
Please have a look at the attached screenshots below.
1. Transferring a single character
2. Transferring a file:
If you are using the DVK, try the below pins which is tapped out directly from the SCBs.
Best Regards,
Yatheesh
