b. Drivers. Inverting amplifiers are used to amplify the low level micro-
computer outputs to control high power loads, such as motors.
c.
Operating Loads.
First the CPU reads the program in ROM. ROM outputs a command to drive a load to
the CPU. The CPU addresses the appropriate I/0 port. The I/0 port passes the drive
command to the driver which amplifies the command and drives the load.
d. Reading of Input Sensors/Commands.
To be sure that the command is being conducted, a feedback loop is employed. A
sensor outputs a sensor signal through the sensor detection I/0 port and CPU. The
CPU will address the program in the RAM or ROM. The RAM or ROM will then output a
command to either continue or stop the action to the CPU. The CPU will address the
appropriate I/0 port to obey the command.
