Notes:
1.Clear Totalizers:
flag from the 8051 to clear either the Channel 1 or Channel 2 totalizers.
2.MODBUS baud rate:
5 = 2400, 6 = 4800, 7 = 9600
3.MODBUS parity:
0 = none, 1 = odd, 2 = even
4.MODBUS stop bits:
1 = 1 stop bit, 2 = 2 stop bits
5.AVG Error Code:
0=Both Ch1 and Ch2 are in error.
1=Ch1 only is in error
2=Ch2 only is in error
3=Both channels are error free
