◆ load_usb_blaster_firmware()

static |
A host loader program must write 0x01 to the CPUCS register to put the CPU into RESET, load all or part of the EZUSB RAM with firmware, then reload the CPUCS register with ‘0’ to take the CPU out of RESET. The CPUCS register (at 0xE600) is the only EZ-USB register that can be written using the Firmware Download command.
