M-Station Baseboard
The SIO method also requires connection of the SCK serial clock, driven by the SCK output on
the USB interface.
2.
When using the UART method, set JP8 and JP9 for UART configuration by connecting pins
1–on each of JP8 and JP9.
• For JP8, this connects the TXD_SO output signal on the flash-programming interface to the
TXD UART output on the USB interface, labeled "UTXD" on the M-Station.
• For JP9, this connects the RXD_SI input on the flash-programming interface to the RXD
UART input on the USB interface, labeled "URXD".
With the UART method, it is not necessary to connect the SCK output on the flash
programming interface to the CPU chip.
When using either a source-level debugger or a micro-board to develop a program that communicates
through a UART, use the UART method, if available, for convenient flash programming. In this case,
JP8 and JP9 are set to UART configuration rather than changed to SIO for flash programming and
then back again for UART communication.
The micro-board must have its flash programming jumpers set in a way that is compatible with the
settinsg of the M-Station. Refer to the user's manuals for the micro-board and MCU.

UART Communication, JP8 and JP9 Settings
You can use the MSTTERM program to communicate with a user program in the flash device on a
micro-board or target system. In this configuration, the program communicates with the USB interface
on the M-Station through the USB driver and cable; the USB interface then communicates through its
UART port with a compatible UART on the micro-board's CPU.
For UART communication, set JP8 and JP9 to UART configuration with pins 1–2 connected on each
jumper, so that TXD_SO connects to the UTXD UART output of the USB interface and RXD_SI
connects to the URXD UART input of the USB interface.
The jumpers on the micro-board should be set to connect the TXD_SO and RXD_SI signals to UART
pins on the CPU device. Refer to the user's manual for the micro-board for appropriate settings.
