5 OPERATION METHOD OF S5U1C60N15E

5.2 Independent Use of S5U1C60N15E

This section describes operation when using the S5U1C60N15E by itself.
The S5U1C60N15E may be used independently by connecting a power supply to it. Use a 5 V DC regula-
tor (more than 3 A) as an external power supply. Connect it with the correct polarity (+ and -).
(Refer to Section 4.2, "Power Cable Connection".)

5.2.1 Power on/off

Before turning the POWER switch of the S5U1C60N15E on, confirm the following:
(1) The power cable is connected correctly.
(2) The target system is connected correctly.
(3) The ROMs have been installed correctly.
After confirming the above items, turn the POWER switch of the S5U1C60N15E on using the following
procedure:
(1) Turn the regulator on. If the regulator is a variable-voltage type, set the output voltage to 5 V ±10%.
(2) Turn the POWER switch of the S5U1C60N15E on.

5.2.2 Debugging

When the S5U1C60N15E is used alone, it provides the following debugging function. The method of
operation is given below.
• Program free run
When the RESET switch (under the top cover) is pressed, the S5U1C60N15E enters the program run
state, and executes the application program from page 1, step 0.

5.3 Operation When ICE is Connected

This section explains the operation and use of the S5U1C60N15E when it is connected to the ICE.
Set up the S5U1C60N15E as follows when it is connected to the ICE:
(1) Do not connect the power supply.
(2) Keep on turning the POWER switch off.
5.3.1 Power on/off
Power to the S5U1C60N15E 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 S5U1C60N15E off.
5.3.2 Debugging
Debugging is done with the host computer, and the S5U1C60N15E is controlled by the ICE. For the
method of operation, refer to the "S5U1C62000A Manual". The S5U1C60N15E can control the following
four functions:
(1) RESET input
(2) OSC3 CR oscillation frequency adjustment with the OSC3CR control
(3) Pseudo power supply voltage change with the SVDT control
(4) LCD contrast adjustment with the VADJ control
