)
58 Input/
Output
Input
Input Port B GPIO — This GPIO pin can be individually programmed as
an input or output pin.
CAN Receive Data — This is the MSCAN interface input.
After reset, the default state is GPIOB13.
30
The CANRX signal is also brought out on the GPIOB9 pin.
GPIOC0
(ANA0 &
CMPAI3)
24 Input/
Output
Analog
Input
Input Port C GPIO — This GPIO pin can be individually programmed as
an input or output pin.
