S1C63406 TECHNICAL MANUAL
APPENDIX S5U1C63000P MANUAL (PERIPHERAL CIRCUIT BOARD FOR S1C63406)
(3) Functional precautions
<LCD power supply circuit>
There is a finite delay time from the point at which the LCD power supply circuit (LPWR) turns on
until an LCD drive waveform is output. On this board, this delay is set to approx. 125 msec, which
differs from that of the actual IC.
<SVD circuit>
- Although the S1C63406 has a function for detecting externally sourced voltages, this board is unable
to detect externally sourced voltages. The SVD function is realized by artificially varying the power
supply voltage using the VSVD control on this board.
- There is a finite delay time from when the power to the SVD circuit turns on until actual detection of
the voltage. On this board, this delay is set to 61–92 sec, which differs from that of the actual IC.
Refer to Section 4.12, "SVD Circuit", when setting the appropriate wait time for the actual IC.
<Oscillation circuit>
-A wait time is required before oscillation stabilizes after the OSC3 oscillation control circuit (OSCC)
is turned on. On this board, even when OSC3 oscillation is changed (CLKCHG) without a wait time,
OSC3 will function normally. Refer to Section 4.3, "Oscillation Circuit", when setting the appropriate
wait time for the actual IC.
- Use separate instructions to switch the clock from OSC3 to OSC1 and to turn off the OSC3 oscillation
circuit. If executed simultaneously with a single instruction, these operations, although good with
this board, may not function properly well with the actual IC.
- Because the logic level of the oscillation circuit is high, the timing at which the oscillation starts on
this board differs from that of the actual IC.
- This board contains oscillation circuits for OSC1 and OSC3. Keep in mind that even though the
actual IC may not have a resonator connected to its OSC3, its emulator can operate with the OSC3
circuit.
- It is necessary to select the appropriate operating voltage for the internal circuits before the OSC3
oscillation circuit can be turned on in the actual IC. Be aware that this board can operate normally
even if an illegal voltage is selected.
-When using an external clock for OSC3, adjust the amplitude of the clock to 3.3 V
± 5% and the duty
ratio to 50%
± 10%, and input it to the ECLK3 pin with VSS as the ground.
<Access to undefined address space>
If any undefined space in the S1C63406's internal ROM/RAM or I/O is accessed for data read or write
operations, the read/written value is indeterminate. Additionally, it is important to remain aware that
indeterminate state differs between this board and the actual IC. Note that the ICE (S5U1C63000H1/
S5U1C63000H2) incorporates the program break function caused by accessing to an undefined
address space.
<Reset circuit>
Keep in mind that the operation sequence from when the ICE and this board are powered on until the
time at which the program starts running differs from the sequence from when the actual IC is
powered on till the program starts running. This is because this board becomes capable of operating
as a debugging system after the user program and optional data are downloaded. When operating the
ICE after placing it in free-running mode, always apply a system reset. A system reset can be per-
formed by pressing the reset switch on this board, by a reset pin input, or by holding the input ports
low simultaneously.
