5.2 Independent Use of S5U1C62N51E1
This section describes operation when using the S5U1C62N51E1 by itself.
The S5U1C62N51E1 may be used independently by connecting a power supply to it. Use a 5 V DC regulator (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 S5U1C62N51E1 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 S5U1C62N51E1 on using the following proce-
dure:
(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 S5U1C62N51E1 on.
5.2.2 Debugging
When the S5U1C62N51E1 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 S5U1C62N51E1 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 S5U1C62N51E1 when it is connected to the ICE.
Set up the S5U1C62N51E1 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 S5U1C62N51E1 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 S5U1C62N51E1 off.
5.3.2 Debugging
Debugging is done with the host computer, and the S5U1C62N51E1 is controlled by the ICE. For the method of
operation, refer to the development tool manual for the S1C62N51, 6S3N7, 60N01, 60N02 or 60N05. The
S5U1C62N51E1 can control the following two functions:
(1) RESET switch
(2) OSC1 CR oscillation frequency adjustment
