NOTE: To use the board in stand-alone operation when powered from the USB cable, remove
the shunt at position “B” and the shunt at position “I”. The shunt at position “J” must
remain ON. Other shunt positions are “Don’t Care”.
Data Rate
The data rate over the USB bus is controlled by the USB_SPEED header. When shipped from
the factory, the DEMO908QC16 is configured for high-speed operation. If the user encounters
a communication failure, data rate may be reduced by setting this option jumper to Full.

MON08 Header
A MON08 compatible programming cable may be attach to the 16-pin MON08 port. Use of
this port requires the user to install a 2x8, 01” center, pin header. Use of this feature requires
an externally powered MON08 cable. The terminal program used with the MON08 cable
should be set to a baud rate of 9600. Set handshaking as required by the terminal MON08
cable used. Refer to MC68HC908QC16 documentation for further details.

NOTE: When using and external MON08 cable, disable the integrated USB-MON08 debugger
by removing all jumpers on the USB-MON08 ENABLE header.
NOTE: This header is not installed in default configuration.
VTST_EN
VTST voltage level is not provided on this board. The MON08 debug cable used must provide
all configuration voltage levels necessary to force the MCU into MON08 mode.
