Command
= 0x17 = 00010111
bin
:
• Bit 0 = 1 (end of transmission)
• Bit 1 ... bit 3 = 011
bin
(3 bytes do not contain any data)
• Bit 4 = 1 (toggle bit)
Influence of the end bit and the remaining data length on the transmission command
• The end of transmission is indicated by the set end bit 0.
• Bits 1 ... 3 indicate the number of bytes which do not contain any data.
* toggle bit
Data 1 ... 7 = "0.00" (ASCII representation)
The result of the data block transmission is: "01.00.00.00"
