I am currently trying to get the PSC3 port to run in UART mode.  Nothing seems to be transmitting.  I have PSC0-PSC2 running in UART mode.  Is there something additional I need to do with PSC3 that is different from the configuration for the other 3 uart ports (PSC0-PSC2).  I have tried setting the PAR_DSPI to 0, with no luck.
Additional info: I have tried to run PSC3 strictly in internal loopback mode as well...that does not work either.  All other ports (PSC0-PSC2) work in internal loopback.  I am using the MCF5475, but iif someone has experienced similar problems on the 548X flavors that may help.
Any help would be greatly appreciated.  Thanks in advance
