描述

In the 7 Series Transceivers Wizard, when 8B/10B and comma detection are selected, RXPCOMMAALIGNEN and RXMCOMMAALIGNEN are unchecked and RXSLIDE is checked by default.

解决方案

This happens when Start From Scratch is selected as the default from the Protocol drop-down list.

You should uncheck RXSLIDE and manually check RXPCOMMAALIGNEN and RXMCOMMAALIGNEN if comma alignment is to be used.

If this is not done, RXPCOMMAALIGNEN and RXMCOMMAALIGNEN will be tied to ground and comma alignment will not work.
