#155715 - PCON Register on AT89C52 |
I am trying to set the baud rate on the AT89C52, making use of the Timer 1 auto-reload mode.
I was trying to set the SMOD bit (bit 7) in the TCON register to double the rate but whenever I go to set it as below:- mov PCON, #10000000b it just hangs forever. Is there anyting else I should be setting/clearing before using the SMOD bit? |
