• VADJ
This is the control for adjusting the LCD contrast. (Refer to Section 6.2, "Differences from Actual IC".)
• SVDT
This is the control for varying the power supply voltage in simulation to check SVD operation. (Refer
to Section 6.2, "Differences from Actual IC".)

LEDs
• POWER This LED lights when the S5U1C60N15E goes on.
• HLT/SLP This LED lights when the CPU enters HALT status.
• AD0 This LED indicates the status of the address 0 (AD0) signal. It can be used to check
whether or not the S5U1C60N15E works.
• SHEXLD This LED lights when segment option data from a personal computer is loaded
using the in-circuit emulator ICE. As the result, it can differentiate whether the
currently specified segment option is due to the ROM (S.HEX) or has been loaded
from a personal computer. Refer to the "S5U1C62000A Manual" in regard to the
loading of the segment option using the ICE.
• LED1 (OSCC) This LED lights when the OSCC register (address 2FEH•D1) is set to "1" and goes
off when the register is set to "0".
• LED2 (CLKCHG) This LED lights when the CLKCHG register (address 2FEH•D2) is set to "1" and
goes off when the register is set to "0".
• LED3 (SVDON) This LED lights when the SVDON register (address 2FFH•D3) is set to "1" and
goes off when the register is set to "0".
• LED4 (HVLD) This LED lights when the HLMOD register (address 2E6H•D3) is set to "1" and
goes off when the register is set to "0".
This LED lights when function option data from a personal computer is loaded
• LED5 (LFHX)
using the in-circuit emulator ICE. As the result, it can differentiate whether the
currently specified function option is due to the ROM (F.HEX) or has been loaded
from a personal computer. Refer to the "S5U1C62000A Manual" in regard to the
loading of the function option using the ICE.
• LED7 (LOF) This LED lights when the LOF register (address 2D0H•D0) is set to "0" and goes
off when the register is set to "1".
• LED8 (SWRUN) This LED lights when the SWRUN register (address 2EEH•D2) is set to "1" and
goes off when the register is set to "0".
• LED9 (DONE) This LED lights when the S5U1C60N15E has completed configuration at power-on
and is ready for debugging. If this LED does not light several seconds after power-
on, turn the power off and then on again.
Test pins
The status of the following signals can be checked by an oscilloscope or other instrument.
• SUB BOARD CONNECTOR Pin 10 (OSC3CR)
This pin is used to monitor the OSC3 CR oscillation clock.
• SUB BOARD CONNECTOR Pin 11 (OSC3CE)
This pin is used to monitor the OSC3 ceramic oscillation clock.
