Chapter 2 Principles of Operation

 

CPU (80C154)

- The CPU 80C154 is a one chip controller linked to many CPU peripheral units. The 
Controller uses an INT Timer

- Interrupt Controller: INT0 and INT1 are used to request an interrupt. The interrupt 

Controller has been programmed so that proper processing is selected 

when a signal is 

input according to an internal table of the CPU.
