Hall Sensor / DAC Interface

Connector J12 offers access to the PAC5532 resources on PORTD utilized for hall sensor based
commutation. These resources can be alternatively utilized as PWM DAC outputs for in real time debugging.
Jumpers JMP1/2/3 are used to select the preferred function.
NOTE: 2 pin shunts must be placed on the JMP1/2/3 in order for the respective PORTD resources to be
made available.
