Question: Design the serial interface between PC-104 and a Micro Controller: PC-104 computer has an available range of [180h to 187h] in ISA bus (IO space).
Design the serial interface between PC-104 and a Micro Controller: PC-104 computer has an available range of [180h to 187h] in ISA bus (IO space). Design an Extra Communication Card with an UART8250 chips in order to communicate to a micro controller card. Draw a diagram that describes this communication, with:
ISA bus: 8 data bit, 10 address A0 to A9, AEN (is low when CPUs bus cycles), /IOR, /IOW, Reset and IRQ7
With logic gates (or PLD Generic Array Logic chip), create addressing decoder for this URART card,
Use a chip as RS232 level driver and receiver for Tx and Rx
