i want to know only that which pin of l293d ic is connected to 89s52 microcontroller which gives the pwm output

The is above seems to indicate you are using a pre-made board, if you do not have the schematic, trace the signal. BTW if you do not have the schematic you should not have bought the board.

If is should have been "to be" then READ THE DATSHEETS.
