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 individual blocks are toggled successively, i.e. first the request with command "0x60" is
effected (= 0110*0000
bin
), then command "0x70" (= 0111*0000
bin
), then "0x60" again, etc.
