POWER
The DEMO9S08LG32 uses several methods to apply power to the board. An option header
allows selection between the various power inputs. For application development and debug,
the board may be powered from the USB BDM. The 2.0mm, center-positive, barrel connector
(VIN) supports stand-alone operation and higher power requirements. Power may also be
applied to connector J1 or the board may be configured to supply power from connector J1 to
external circuitry.
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: the PWE_SEL option header and the VX_EN option header.
PWR_SEL
The PWR_SEL option header allows the user to select power input either from either an
external power source connected to the VIN connector or from the integrated USB-BDM.
Figure 4 below details the PWR_SEL header connections.
