Programming & erasing flash memory of microcontroller through parallel port of pc

Hi, I am a student of computer science. I am new in embedded world. I have some MAC7121 microcontroller. Can write the flash memory of that microcontroller through parallel port of pc(Using some external circuit). If I can then please explain the way & give necessary links. Also give info about external circuit if it is necessary. If I can't is any 32 bit microcontroller exists in whose flash memory/EEPROM I can write through parallel port. Please infom.

You can Jtag program the chip as long as you have the proper level shifters. The Mac7121 is 2.5V and parallel port is 5V logic. Straight connect will surely burn out the chip.
