BDM_PORT Header
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
the pin-out for the DEBUG header. This information is included for completeness.

POWER
The DEMO9S08SH32/SG32 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. Optionally, the board may be powered from the LIN connectors.
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 or from the LIN bus.
POWER SELECT
Power may be applied to the board through the integrated USB-Multilink BDM circuitry, a
2.0mm barrel connector, or through connector J1.
selection headers: PWR_SEL option header and the VX_EN option header.
PWR_SEL
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.
