The function differs between ICD mode and Flash programmer mode.
In ICD mode
Click:
The firmware restarts and performs the initial sequence for connecting with the S1C processor on the
target system. If the target board has not been connected physically, the S5U1C17001H enters initial
connection waiting status.
When the TARGET RST OUT signal of the S5U1C17001H has been connected to the target system, a
reset signal is output to the target system simultaneously.
In Flash programmer mode
Click:
The S5U1C17001H starts the selected Flash operation (erasing, programming, verification).
If the LED for the operation to be executed indicates OK or ERR, a hardware reset will return to default
state.
Press and hold (about three seconds):
Issues a hardware reset to the S5U1C17001H.
Note: When a DIP switch setting is changed, it will take effect by pressing the RESET/START switch (in
both ICD and Flash programmer modes).
