8254 Programmable Interval Timer - SlideServe

Design a programmable timer using 8254 and 8086 . Interface 8254 at an address 0040 H for counter 0 and write the following ALPs. The 8086 and 8254 run at 6 MHz and 1.5 MHz respectively. (i) To generate a square wave of period 1 ms . olution Neglecting the higher order address lines (A16-A8), the interfacing circuit diagram is shown in Fig. The 8254 is interfaced with lower order data bus ( .D0-D7), hence A0 is used for selecting the even bank. The A0 and A1 of the 8254 are connected with A1 and
