What is the highest USBRX/USBTX baud rate ?

Is it possible to use baud rates above 115200 for communication with LPC11U35 ?

Try it out? I know on the LPC1768 I have used it fine up to 921600.

LPC11U35 on C027 uses 12MHz clock, so 921600 is too high for it: 12000000/16/(115200*8)=0.813802 I will try 460800 12000000/16/(115200*4)=1.6276 which should be ok for the 5/8 fractional divider. Hopefully the autobauding will work at this speed.

After the successful runs of the TransparentGPS program, i can confirm that both 230400 and 460800 baud rates work on C027.
