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.
A.2 Names and Functions of Each Part
The following describes the parts layout on the S5U1C330MxD1 board as well as the functions of the connectors and
switches:
RS232 connector
OFF ON

(RESET)
SW2

S5U1C33xxxDx/target board I/F connector
Figure A.2.1 S5U1C330MxD1 board layout
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"
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:

S1C33 FAMILY DEBUG MONITOR
OPERATION MANUAL
SW1 (RESET switch)
Sets up the status of the RESET pin at the S5U1C33xxxDx/
target board I/F connector. When a S5U1C33xxxDx board is
OFF ON
connected, this switch can reset the CPU on the board.
SW3
ON: RESET = "0"
(DEBUG)
SW2 (NMI switch)
Sets up the status of the NMI pin at the S5U1C33xxxDx/target
12
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: DEBUG (K63) = "1"
No. Signal name

( ) indicates the CPU pin corresponding to the signal
when the S5U1C33104Dx/S5U1C33209Dx is
connected.
Since the corresponding signals on the
S5U1C33xxxDx may differ depending on the
board, refer to the pin layout table provided in
the specifications of each S5U1C33xxxDx board.
