The data in the counter read register, and the action taken on the data in a counter load register, is wholly dependent upon the
control code written to the control register.
The counters are 16-bit counters, each with an 8-bit window, the read / load register. Data is shifted into and out of the 16-bit
counters through these 8-bit windows according to the control byte.
You will need an 8254 data sheet if you want to program the 8254 directly at the register level.
