Serial Port

Vikas Pachpute

Serial Port in Mode 1 and Timer 1

I am using P89V51RD2 microcontroller.I configured Serial port in Mode 1(Auto baud Rate Generation) with Timer 1.

In this configuration communication is working.But when micrcontroller sending data it make MSB bit of data High.So if I am sending 0x13H,I am getting 0x93H

0x32H - 0xB2H
0x33H - 0xB3H

But same configuration with Timer 2 is working very perfectly.

So where should I check?
