Explanations on the telegram to the drive
Command = 0x60 = "Read segment request" (request: read data block)
• Bit 4 = 0 (toggle bit)
Influence of the toggle bit on the request command
The single blocks are toggled one after another, i.e. first the request is made with the "0x60"
command (= 0b0110*0000), then with the "0x70" command (= 0b0111*0000), and then again
with the "0x60" command, etc.
