Appendix S5U1C330MxD1 Board

This chapter describes how to use the S5U1C330MxD1 board.

A.1 Outline of S5U1C330MxD1 Board

 

The S5U1C330MxD1 board provides the interface for the debug

 

monitor to the demonstration tools such as the S5U1C33104Dx or the

 

user target board. The S5U1C330MxD1 allows on-board debugging

 

using the debugger (db33.exe) on a personal computer by connecting

 

it to the target board in which the S1C33 Family debug monitor

 

(S5U1C330M2S) has been implemented.

 

Two types of boards are available: S5U1C330M1D1 board for 5 V

 

operation and S5U1C330M2D1 for 3.3 V operation.

SW1 (RESET switch)

Sets up the status of the RESET pin at the S5U1C33xxxDx/ target board I/F connector. When a S5U1C33xxxDx board is connected, this switch can reset the CPU on the board.

ON: RESET = "0" OFF: RESET = "1"

SW2 (NMI switch)

Sets up the status of the NMI pin at the S5U1C33xxxDx/target board I/F connector. When a S5U1C33xxxDx board is connected, a NMI request can be input to the CPU on the

board.

 

ON: NMI = "0"

OFF: NMI = "1"

SW3 (DEBUG switch)

Sets up the status of the DEBUG pin at the S5U1C33xxxDx/target board I/F connector. When the S5U1C33104Dx/S5U1C33209Dx board is connected, the switch signal is input to the K63 port and can be used to start up the debug monitor from the boot routine.

ON: DEBUG (K63) = "0" OFF: DEBUG (K63) = "1"

When the switch is ON, the S5U1C33104Dx/S5U1C33209Dx will start the debug monitor. When the switch is OFF, the S5U1C33104Dx/S5U1C33209Dx will start executing the program stored in the Flash memory. The S5U1C33104Dx/S5U1C33209Dx works assuming the debug switch is OFF when the S5U1C330MxD1 is not connected.

RS232C connector

This is a Dsub 9-pin connector for connecting a personal computer. Use the RS232C cable supplied with the S5U1C330MxD1 package for connection.

S5U1C33xxxDx/target board I/F connector

This connector is used for connecting the S5U1C33xxxDx board. The pin layout is as follows:
