Question

Write an assembly language program to generate square wave mode 2 on a port pin

Answer 1

Answer:

Explanation:

Look at the following steps.

T — 1 / 50 Hz = 20 ms, the period of the square wave.

1/2 of it for the high and low portions of the pulse = 10 ms

10 ms / 1.085 us = 9216 and 65536 – 9216 = 56320 in decimal, and in hex it is

DCOOH.

TL = 00 and TH = DC (hex)
