How do you know that c places the dats byte in the accumulator
Erik I used the Keil debugger and verified the instructions step by step and the 'C' does place the byte in the accumulator and calculate the parity correctly.The problem is with the TB8_0 bit being transmitted after 8 bits of data is transmitted.I am not able to amke out whether TB8_0 bit is transmitted or not. Moreover, irrespective of TB8_0 being transmitted or not, the Hyperterminal or any software for that matter(used for serial communication) is recognizing the data sent.Actually speaking, when I set the configuration on hyperterminal as 9600,1,even,8........... a byte (say for example, 01010101) which has even parity,will have a parity bit added to it and be transmitted as 01010101 + 1 parity bit.....and the hyperterminal being configured as 9600,1,odd,8 should be able to recognize it. But when I change the configuration of hyperterminal as 9600,1,Odd,8 it should not recognize 01010101 + 1 ........ In my case the hyperterminal is recognizing the byte as 0x55!!!! How is this possible?? |
