Communications
The DEMOAC board provides 2 UART ports, 1 IIC port, and 1 CAN port. Serial RS-232 com-
munications is support through the integrated BDM. Access to each MCU UART is also avail-
able at connector J1. RS-232 translation is not provided on signals to connector J1.
Virtual COM Port
The serial link through the integrated USB BDM is implemented as a virtual COM port running
through the USB connection. Use of this link require installation of the P&E Micro Demo Board
Toolkit. This toolkit is available on the DVD provided with the DEMOAC.
Refer to the P&E documentation for details and instructions on use of the virtual COM port.
COM_EN
The USB_COM option header individually connects and disconnects the target UART signals
to the integrated USB BDM. Removing a shunt disconnects the associated signal. Installing a
shunt connects the associated signal.

CAN Port
CAN port signals connect directly between the target MCU and the MCU Port connector at J1.
Refer to the target MCU device Reference Manual for details on using this feature.
IIC Port
IIC port signals connect directly between the target MCU and the MCU Port connector at J1.
Refer to the target MCU device Reference Manual for details on using this feature. Each IIC
signal is pulled up to VDD at the I2C_PULL_EN option header.
