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.
Jumper JMP1/2/3 Description
1:2 Hall Sensor Functionality
2:3 DAC Functionality
NOTE: J12 functionality is only available when jumpers JMP1/2/3 have been shunted on the Hall Sensor
respective position.
