(EVALUATION BOARD FOR S1C60N09/6S3N2/62N33)
5 OPERATION METHOD OF S5U1C6S3N2E2
5.2 Independent Use of S5U1C6S3N2E2
This section describes operation when using the S5U1C6S3N2E2 by itself.
The S5U1C6S3N2E2 may be used independently by connecting a power supply to it. Use a 5 V DC
regulator (more than 3 A) or the AC adaptor supplied with the ICE as an external power supply. When
using 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 S5U1C6S3N2E2 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 S5U1C6S3N2E2 on using the following
procedure. When turning the S5U1C6S3N2E2 off, follow the procedure from (2) to (1):
(1) Turn the regulator on and set the output voltage to 5 V ±10%.
When using the AC adaptor, plug the AC adaptor into the AC line and the S5U1C6S3N2E2.
(2) Turn the POWER switch of the S5U1C6S3N2E2 on.
5.2.2 Debugging
When the S5U1C6S3N2E2 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 S5U1C6S3N2E2 enters the program run
state, and executes the application program from page 1, step 0.
• Other functions
The SVD operation can be confirmed with the VSVD control.*
The LCD contrast can be adjusted with the VADJ control. (Refer to Section 6.2, "Differences from
Actual IC".)
The HVLD (HLMOD), SVDON (BLS)*, OSCC*, AMPON*, CSDC, SWRUN and EVRUN* resister
values can be confirmed with the LED indicators and the monitor pins.
∗ These functions can be used when the S5U1C6S3N2E2 is set for the S1C6S3N2 or the S1C62N33.
5.3 Operation When ICE is Connected
This section explains the operation and use of the S5U1C6S3N2E2 when it is connected to the ICE. Set up
the S5U1C6S3N2E2 as follows when it is connected to the ICE:
(1) Do not connect the power supply and the AC adaptor.
(2) Keep on turning the POWER switch off.
5.3.1 Power on/off
Power to the S5U1C6S3N2E2 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 S5U1C6S3N2E2 off.
5.3.2 Debugging
Debugging is done with the host computer, and the S5U1C6S3N2E2 is controlled by the ICE. For the
method of operation, refer to the "S5U1C62000A Manual" and the "S5U1C62xxxD Manual". The
S5U1C6S3N2E2 can control the following three functions:
(1) Pseudo power supply voltage change with the VSVD control *
(2) LCD contrast adjustment with the VADJ control
(3) RESET switch
∗ This function can be used when the S5U1C6S3N2E2 is set for the S1C6S3N2 or the S1C62N33.
