M-Station Baseboard

3.7.7

Row 1

Row 1 is used to bring in CPU signals that can be jumper connected from the hardware resources on

row 2. When a micro-board is designed, the required UART or port signals are lined up with row 2 so

that the necessary hardware resources may be used for application development and debugging.

3.7.8

Row 3 is used to connect to optional 64 KB external expansion SRAM. The signals for ports 4, 5, and

6 of the CPU are connected to row 3.

3.8

The CPU signals are connected to the 100-pin P1 and P2 connectors on the micro-board and the 100-

pin J1 and J2 connectors on the M-Station. From J1 and J2, the CPU signals are routed to rows in the

user breadboarding area.

The signals that are necessary to be used for "Application Development Aid Hardware Resources" are

pre-assigned so that they can be placed on row 1, where they can be jumper connected to row 2. For

example, UART signals are connected to row 1[1:4] so that row 2[1:4] can be jumper connected. If

there is an additional UART, the signal for the second UART will be connected to row 3[1:4]. At your

option, row 2[1:4] can be connected to row 3[1:4]. Refer to the user's manual for your micro-board.

1. UART0 and UART3 signals are connected to preset positions on P1/P2.

2. UART0 and UART3 signals are routed to rows 1 and 3.

3. Selected UART signals can be jumper-connected from row 2.
