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 |
|
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. | Figure A.1.1 S5U1C330MxD1 board |

S5U1C33xxxDx/target board I/F connector
Figure A.2.1 S5U1C330MxD1 board layout
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" |
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 connectorThis is a Dsub
This connector is used for connecting the S5U1C33xxxDx board. The pin layout is as follows:
Table A.2.1 S5U1C33xxxDx/target board connector pin layout
No. | Signal name | No. | Signal name | ( ) indicates the CPU pin corresponding to the signal |
1 | VCC [+5 V, +3.3 V] | 7 | N.C. | when the S5U1C33104Dx/S5U1C33209Dx is |
2 | VCC [+5 V, +3.3 V] | 8 | DEBUG (K63) | connected. |
3 | RESET (#RESET) | 9 | VCC [+5 V, +3.3 V] | Since the corresponding signals on the |
4 | TxD (P05) | 10 | SCLK (P06) | S5U1C33xxxDx may differ depending on the |
5 | RxD (P04) | 11 | GND | board, refer to the pin layout table provided in |
6 | NMI (#NMI) | 12 | GND | the specifications of each S5U1C33xxxDx board. |
