6 Utilize an Alternative Microcontroller
The expansion I/O connector, JP9, allows users to apply an alternative microcontroller
to drive the motor, for example, the Infineon C166 series microcontrollers with integrated
CAPCOM6(E) PWM units such as the XC164.
The signals of the expansion I/O JP9 are described in the following table:

2COUT0 First phase low side PWM signal
3CC1 Second phase high side PWM signal
4COUT1 Second phase low side PWM signal
5CC2 Third phase high side PWM signal
6COUT2 Third phase low side PWM signal
7CTRAP Over current trap signal
