EVALUATION BOARD S5U1C62XXXE

•Single step

By pressing the STEP key after a program break, the one instruction at the current address can be executed, and the program stopped at the next address (program break). Using this function, the program run state can be confirmed.

For the other functions, refer to the "S5U1C62xxxE Manual".

6.3 Operation When ICE (S5U1C62000H) is Connected

This section explains the operation and use of the S5U1C62xxxE when it is connected to the ICE. Set up the S5U1C62xxxE as follows when it is connected to the ICE:

(1)Do not connect the power supply.

(2)Keep on turning the POWER switch off.

(3)Set all the switches on the operation panel to their lower positions.

6.3.1Power on/off

Power to the S5U1C62xxxE is supplied by the ICE, and the power is switched on and off by pressing the POWER switch of the ICE. Keep the POWER switch of the S5U1C62xxxE off.

Note: To turn the POWER switch of the ICE off, then on, turn it off, wait for 10 seconds or more, and then turn it on.

After the POWER switch of the ICE has been turned on, the DONE LED (green) on the top cover of the S5U1C62xxxE lights after several seconds to indicate that debugging may proceed. If the DONE LED is still off 10 seconds or more after the POWER switch has been turned on, do the following:

(1)Turn the POWER switch of the ICE off.

(2)Confirm that the circuit breaker of the ICE is on.

(3)Confirm that the ROMs have been installed properly and the cables connected properly.

(4)Turn the POWER switch of the ICE on.

If the DONE LED still does not light, do a self-diagnosis.

For the self-diagnosis method, refer to the "S5U1C62xxxE Manual".

6.3.2Debugging

Debugging is done with the host computer, and the S5U1C62xxxE is controlled by the ICE. For the method of operation, refer to Part VIII, "ICE Control Software ICS62XX".

The switches except the reset switch and LEDs are invalid. Do not operate the switches of the S5U1C62xxxE side. The target program ROM is invalid when the ROM is installed.

7 OPERATING TEST

Self-diagnosis of the S5U1C62xxxE can be performed with the following operating tests. To perform these tests, the function option ROM, two segment ROMs and two program ROMs (supplied) are required. If these ROMs have not been installed, insert them into the sockets. To use the S5U1C62xxxE independently, connect the external power supply (5 V DC, 3 A).

Refer to the "S5U1C62xxxE Manual" for details of the operating test.
