Firmware data is transferred from the host to the unit using CHK GUARD and WRITE_FIRM commands. For
dataSize to be transferred, specify a value of less than windowSize set to the Response data that was issued just
before transfer. When transmitting a command first, issue a command (with dataSize set to "0") without sending
firmData and then issue a command for transferring data actually after confirming windowSize set to the
Response data. Transmit data continuously until commands other than STAT_BUSY are returned.
Description
