 		 #90663 - Baud config Winbond W78E52B
Hi There,
I am trying to configure the serial port Baud rate of my Winbond W78E52B. I use the code below.
Save This Code
mov SCON, #01010000b
mov PCON, #10000000b       				
mov TMOD, #00100000b       			  
mov TL1,  #-3
mov TH1,  #-3

If I do not set PCON.7, the serial port runs at 9600 Baud perfectly. However if I set PCON.7 (like in the code above), the port should run at 19200 Baud. This however doesn't seem to be the case. Furtermore, trying to configure other rates (e.g. 1200 or 2400 Baud ) fails.
I send data to the processor using a LAWN radio data link, which should be capable of sending data with a rate up to 19200 Baud.
Do I overlook something?
