4.5.4 Firmware Upgrade

The settings in the Firmware upgrade category can be used to erase the current firmware, to upload
new firmware, to program new firmware into flash memory and to verify the uploaded firmware.
To upgrade the DTM-3237B, setting Mode (0x01) needs to be set to '1' (Firmware upgrade mode).
When the USB interface is used and Mode is changed, a USB reconnect is necessary.
The new firmware has to be uploaded in "file parts". For communication through I
contain at most 250 data-bytes; for communication through USB or LVTTL serial control port the parts
may contain at most 1000 data bytes.
An example of a firmware upgrade sequence can be found in paragraph 4.6.
