Command
= 0x60 = "read segment request" (request to read the data block)
• Bit 4 = 0 (toggle bit)
Influence of the toggle bit on the request command
The individual blocks are toggled in turn, i.e. first the request with the command "0x60" (=
0110*0000
bin
), then the one with the command "0x70" (= 0111*0000
bin
), then "0x60" again, etc.
