Abstract
A monitor program stored in a ROM of a microcomputer chip of a computer is operated both to (1) save power by disabling all external buses, turning off power to a communication port, deselecting all external memory devices, and turning off a fast clock oscillator and clocking all operations of the microcomputer chip at a slow second frequency, and also to (2) prioritize execution of a plurality of application programs located in external memory devices and/or internal memory of the microcomputer chip while also relying on the monitor program to effectuate normal initialization procedures. The monitor program also allows efficient access to slow external memory devices by dividing down the fast clock rate produced by the oscillator to a slower rate and accessing the slow memory at the slower rate, thereby saving power.
