4.2.2 RESET/START switch
< In ICD mode >
Pressing the RESET/START switch restarts the firmware and establishes an initial
connection with the target S1C processor. If the target board is not connected, the firmware
awaits the initial connection. If the TARGET RST OUTPUT signal from the
S5U1C33001H reaches the target board, a reset signal is also output.
< In flash programmer mode >
Pressing the RESET/START switch invokes the selected flash operation function (erase,
write, verify). If the LED indicates OK/ERR, the state immediately before the execution of
the function will be restored.
Note: After operating the DIP switches, press the RESET/START switch to apply the
settings (in ICD mode or flash programmer mode).
4.2.3 USB connector
This con
nector is used to connect a PC using the USB cable.
Note: A USB hub that runs solely on bus power may not provide adequate power in all
cases. To supply voltage for flash programming to the target system in flash
programmer mode, connect directly to the USB port of the PC or use an AC adaptor
(USB 5-V output) to supply power to the USB cable.
