Import PLL Frequency Launches Incorrect Parameter Editor

Description

If you click Import PLL Frequency, the ALTLVDS_TX parameter editor correctly starts, but you can incorrectly edit all parameters not just the Frequency /PLL Settings page parameters.

This issue affects all configurations.

There is no design impact.

Resolution

To work around this issue, when the ALTLVDS_TX parameter editor starts on the General parameters page, follow these steps:

1. Click Next to go to the Frequency/PLL Settings page.
2. Select desired input clock rate.
3. Click Finish twice to skip the remaining pages and close the ALTLVDS_TX parameter editor.

This issue will be fixed in a future version of the POS-PHY Level 4 MegaCore function.
