PRODUCTION DATA
The MCF8329A provides information about the motor speed through the Frequency Generate (FG) pin. In MCF8329A, the FG pin output is configured through FG_CONFIG. When FG_CONFIG is configured to 0b, the FG output is active as long as the MCF8329A is driving the motor. When FG_CONFIG is configured to 1b, the MCF8329A provides an FG output as long as the MCF8329A is driving the motor and also during coasting until the motor back-EMF falls below the threshold configured by FG_BEMF_THR.
