The POSIF module is comprised of three major sub units, the Quadrature Decoder unit, the Hall Sensor Control unit and the Multi-Channel Mode unit with the following features

Quadrature Decoder (used for position control linked with a rotary incremental encoder.)
– interface for position measurement
– interface for motor revolution measurement
– interface for velocity measurement
– interrupt sources for phase error, motor revolution, direction change and error on phase decoding

Hall Sensor Mode (used for direct control of brushless DC motors.)
– Simple build-in mode for brushless DC motor control
– Shadow register for the multi-channel pattern
– Complete synchronization with the PWM signals and the multi-channel pattern update
– interrupt sources for Correct Hall Event detection, Wrong Hall Event Detection

Multi-Channel Mode (used in conjunction with the Hall Sensor mode to output the wanted motor control pattern)
– Simple usage with Hall Sensor Mode
– stand-alone Multi-Channel mode
– Shadow register for the multi-channel pattern
