M-Station Baseboard
3.2
Flash Programming Connections
The 16-pin J4 flash programming/debugging header can be used to program on-chip flash memory on
the micro-boards without having to connect the board and M-Station through the 100-pin connectors.
The 16-pin header also can be used for in-system programming of the MCU on your target system,
provided the target has a 16-pin interface header to connect to the M-Station. Figure 4 shows the
arrangement for the 16-pin cable connection.
Please refer to the flash programming section of the user’s manual for your MCU for information about
designing the target interface for flash programming.

V
DD
Power Source Selection
The JP2 jumper selects the source of the V
DD
power on the M-Station. Connecting JP2 pins 1 to 2,
marked as “REG” and “V
DD
” respectively on the board, supplies V
DD
from the on-board VDD_SEL
voltage generated by the voltage regulator and selected by JP3.
Connecting JP2 pins 2 to 3, marked as “V
DD
” and “BAT” respectively on the board, supplies V
DD
from
the optional battery pack on the underside of the M-Station baseboard. This allows the M-Station
baseboard and attached micro-board to operate in standalone mode on battery power, rather than with
the 12V power supply connected to the J8 power connector. Operation is possible without the 12V
power supply, but it is required for flash programming.
When V
DD
power is supplied by the micro-board or target system, remove JP2 to avoid potential
conflict between V
DD
levels.
