5213 SYNCA and GPT

I have worked many years with the 5307 and 5282 parts and even with early mask releases the documentation wasn't as bad as the 5213.

The documentation seems to indicate that there is a SYNCA and SYNCB (though there is only one GPT in the 5213). The documentation also states "A high signal on this pin clears the counter".

The GPIO map leads one to believe that there are both SYNCA/SYNCB and can be accessed in places such as PORTUB[3:2] as the second function. I have configured the pins as such and litteraly banged my head on the table trying to get the counter to reset to 0 based on an external sync.

Any ideas would be greatly welcome.
