Timer

Standard PCs as well as the VP7 are equipped with a 8254 compatible timer. This timer contains three
counters.  Each  counter  output  provides  a  key  system  function.  Counter  0  is  connected  to  interrupt
controller  input  IRQ0  and  provides  a  system  timer  interrupt  for  time-of-day,  floppy  disk  timeout  and
other system timing functions. Counter 1 generates a refresh request signal and Counter 2 generates the
sound for the speaker. The following table gives an overview of the 8254 functions.

The  counter/timers  are  programmed  by  I/O  accesses.  A  single  control  word  register  controls  the
operation of all three counters. The register map is shown in the following table:
