2.1.3 JP3: +3.3 V Enable
JP3 option installed (default) provides +3.3V regulated voltage from the onboard VR1 voltage
regulator to power the DEMO board. Open this option to power the board from an external +3.3V
source or from the J1 connector.
regulator to power the DEMO board. Open this option to power the board from an external +3.3V
source or from the J1 connector.
2.1.4 JP4: +Vopt Enable
JP4 option installed provides a connection from J1 pin 1 to the board +3.3V power connection.
This option is open/idle by default. This option may be applied to provide board +3.3 V regulated
voltage to the J1 connector (JP3 installed also) or to source +3.3V from J1 (JP3 open) to power
the board from a connected host platform.

2.1.5 TX_EN and RX_EN Option Jumpers
TX_EN and RX_EN options provide selection of the serial port connection for the MC56F8006 SCI
serial port. MC56F8006 ports B6 (RXD) and B7 (TXD) provide the SCI I/O pins for these options.
Default option setting is for the USB port to support the SCI serial port. The RS-232 serial port is
not populated by default but may be applied by the user if populated.

Default option setting is for the USB port to support the SCI serial port. The RS-232 serial port is
not populated by default but may be applied by the user if populated.
TX_EN and RX_EN = position 1–2 default, USB BDM serial port support.
Position 2–3 = RS-232 port.
See the support DVD for virtual terminal software to support the USB serial port.
2.2 User Components
2.2.1 LED1: 6 Indicators
Six indicator LEDs are provided for user application indications. The LEDs are applied to the
MC56F8006 I/O port A0/PWM0 to A5/PWM5 signals. Buffers are applied so that the LEDs will not
load the I/O port pins during operation. LEDs are on during the applied signals logic high level.
The following table provides the signal and LED reference.
