Is hardware serial synchronized transfer not supported in PBP?

Is hardware serial synchronized transfer not supported in PBP? I only find the HSERIN/HSEROUT commands in PBP manual which is for asynchronous transfer.

Thanks!

Although I do not have an example of it, you can certainly access the USART registers directly using PBP and therefore, use hardware sync serial communication.

Perhaps someone else has an example?

If not, the datasheet is now your new best friend.
