Command management
The host microcontroller can control motor motion and configure the L6470 through a
complete set of commands.
All commands are composed by a single byte. After the command byte, some bytes of
arguments should be needed (see
Figure 20. Command with 3-byte argument
By default, the device returns an all zero response for any received byte, the only exceptions
are the GetParam and GetStatus commands. When one of these commands is received,
the following response bytes represent the related register value (see
length can vary from 1 to 3 bytes.
Figure 21. Command with 3-byte response
During response transmission, new commands can be sent. If a command requiring a
response is sent before the previous response is completed, the response transmission is
aborted and the new response is loaded into the output communication buffer (see
Figure
22).
