Figure 13. Motor 1 c unused MCU pin socket connector pinouts
Jumper JP58, which is placed between signals on pins 16 and 18 of connector J9, is
used to enable/disable pullup resistor control for I3C master.
2.13.2 Motor 2 c Arduino socket
The Motor 2 c Arduino socket allows communication with the following modules of
the target MCU:
•
FlexPWM1 module of motor control subsystem
•
Analog-to-digital converter (ADC) modules, ADC0 and ADC1
•
HS SPI controller
The Motor 2 c Arduino socket is pin-compatible with an Arduino UNO board. The
socket includes the following four connectors:
•
J132 (2x6 position receptacle)
•
J102 (2x8 position receptacle)
•
J92 (2x10 position receptacle)
•
J122 (2x8 position receptacle)
The figure below shows the pinouts of Motor 2 c Arduino socket connectors. Odd
pins (inner side pins) of the socket are used for motor control. Even pins (outer side pins)
of the socket provide connection with an external Arduino board.
