The state diagram in Figure 6-1 illustrates the motor control system and its
interaction with each interrupt service available in the system. The firmware basically
revolves on the state of the motor, whether it is in the Running condition or in Stop
condition. Flags are used to identify the state of motor operation. From Reset, all
peripherals and variables are initialized while keeping interrupts disabled. The motor
is initially set in a Stop state and in a CCW direction. For the complete source code,
refer to Appendix C: Source Code Listing.Figure 6-1 6-2 6-3 6-4. Motor Control State
