6.6 MotorDrive connector
The MotorDrive connector can be used to connect an external power stage for motor control.
It holds the necessary signals for PWM generation and current / voltage measurement.

Pins 13 -18 are spare pins and not used by default. They are connected to the pin header
X13 as well as JP37 and JP39. JP37 can be used to connect OPT1 to Pin27 of the MCU
(INT7/PPG7) in case the external circuit provides e.g. a break resistor which shall be
controlled by PPG7 or an additional interrupt source to be monitored. JP39 connects OPT6
to the analog input AN2-4 (Pin86), e.g. for a temperature sensor.
