A compatible HCS12 BDM cable can also attach to the 6-pin BDM interface header
(BDM_PORT).  This header is not installed in default configuration.  The figure below shows

NOTE:  This header is not installed in default configuration.

The DEMO9S08DZ60 is designed to allow the user to power the board through the USB-
Multilink BDM during application development.  A 2.0-mm barrel connector has been applied to
support stand-alone operation and to support LIN functionality.  The board may also be
powered through connector J1.  This connection may also be used to supply power from the
board to external circuitry.

During application development, the board may be powered from either the USB-BDM or the
PWR connector.  To utilize LIN functionality, the board must be powered from PWR connector
with a typical input voltage of +12VDC.

Power may be applied to the board through the integrated USB-Multilink BDM circuitry, a
2.0mm barrel connector, or through connector J1.  Power selection is achieved using 2
selection headers: PWR_SEL option header and the VX_EN option header.

The PWR_SEL option header selects power input either from the integrated USB-Multilink
BDM circuitry or from the on-board voltage regulator.  The figure below details the PWR_SEL
header connections.

CONFIGURATION

1 – 2: Selects power input from USB-ML12
2 – 3: Selects power input from on-board regulator or J1
