Communications
The EVB51JM128 board provides 2 UART ports, 1 IIC port, and 1 USB OTG port. RS-232
communication is supported through UART[2:0] connectors and through the MCU_PORT con-
nector. IIC communications are supported solely through the MCU_PORT connector. The
COM_EN option header enables SCI functionality between the MCU and the associated
UARTx connector. The COM_EN option header also enables serial communications through
the integrated USB BDM.
COM Ports
An RS-232 transceiver provides RS-232 to TTL/CMOS logic level translation between the
UARTx connector and the MCU. The transceiver provides full RS-232 signaling at input volt-
age level between 3.0V and 5.0V. The COMx connector is a 9-pin Dsub, right-angle connec-
tor. A ferrite bead on shield ground provides conducted immunity protection. Communication
signals TXDx, RXDx are routed from the transceiver to the MCU. These signals are also avail-
able at the MCU_PORT connector. Handshake signals RSTx and CTSx are not available.
COM_EN
The COM_EN option header individually connects and disconnects UARTx signals between
the MCU and the SCI transceiver. Removing a shunt disconnects the associated signal. In-
stalling a shunt connects the associated signal.
