I NEED THE PORCESSOR TO RUN AT 82MHZ BUT THE XTAL IS 13>7242MHZ
HOW DO I PROGRAM C TO GET THE CODE FASTER?
I LOOK IN UVISION AND CHANGE THE FREQ BUT IT DOESNT MAKE CHANGE IN CODE! HAVE I GOT A BUG?
psd934f2 according to ST micro datasheet is a "configurable memory system on a chip for 8-bit microcontrollers"
and that obsolete chip has never neen intended for any use with a '51 other than a 'traditional' running at 12MHz.

ah yes - not to be confused with the modern uPSD range, which includes an 8051 in the package...
