• Manufacturer Part Number: MC56F8366
• Description: 56f8300 16-bit Digital Signal Controllers
• Manufacturer: Freescale Semiconductor, Inc

Two Input/Output pins associated with GPIOD can function as GPIO, EMI (default peripheral) or CAN2
(NOT available in the 56F8166 device) signals. GPIO is the default and is enabled/disabled via the
GPIOD_PER, as shown in
peripheral input/output, then the choice between EMI and CAN2 inputs/outputs is made here in the GPS.
Note: CAN2 is NOT available in the 56F8166 device.
