Hi Every Body

The SMOD bit at UPSD.H is disabled.

When I enable it, the compiler shouts error ''PCON invalid base address''.

How can I enable the SMOD bit in the UPSD.H file?.

Thank you all.

PCON register is NOT bit addressable, only registers reside on addresses x0 and x8 are bit addressable. Although some compilers can use macros to do the bit manipulation; Keil complier does not support it. You need to OR in the bit you want to set or reset.
