here the insystem programable means

 

i think 89C51 can be programed through RXD and TXD serial pins

we connect it to PC db9 port through max232ic and program it with relavent software.but in case of  89S51 it is programed using “master and slave mode”

 

MOSI:master out slave in

 

MISO:master in slave out

 

I think you are using an usb programer for 89S51 that containing an atmega8

microcontroller from AVR family from atmel.this mcu also contains mosi,miso pins.

 

so 89C51 wont support it
