(6) Use the c33 fwld (or c33 fwdc) command to download the data to be written to the target system
flash memory to the S5U1C33001H. At the same time, set the erase area in flash memory.
Example: Erasing all sectors and downloading sample.saf to flash memory
(when flash start address is 0x600000)
(gdb) c33 fwld sample.saf 0 0 0x600000

(2) If the DIP switch settings were changed while power was being supplied via USB, press the
RESET/START switch to set the S5U1C33001H to flash programmer mode.
If the DIP switch settings are changed when power is off, supply power by connecting the USB
cable for the S5U1C33001H to the USB port of the host computer or by connecting an AC
adaptor with USB 5-V output. (Flash programmer mode will run on power supplied through the
USB cable. No communication occurs with the PC.) If the S5U1C33001H starts up properly, the
LEDs will light up according to the selected operating mode.
