Hi all,
I'm trying to set up uart2 on a MCF52221, but in MCF52221_GPIO.h file I cannot find any macro for Port UC. There are macros for PUA and PUB, but nothing referred to PUC.
There is something wrong on thereference manual or is only a problem of .h file?
Thanks

The info there is correct.

The PORTUC pins are only available on a 100 pin package.
The MCF52221 is not available in this package according to the Ref Manual.
The website then again says it is available in 100 pins packages.
Thank you very much. This means that there isn't UART2 on the demo board CPU.
Hi
On 80 pin devices UART2 is still available as alternative peripheral on port AS.

Indeed, and those UART2 pins on PORTAS pins are available on the I/O port connector J1.
No level RS232 converter there. Use an external one if needed.
If UART2 is used, you will have to give up on CTS1/RTS1 or move those to PORTQS, giving up on QSPI.
