RETURN SETTING Command (CMD7 - 0 = 000P - 0001 = 01h or 11h)
Operation:
This command is ignored after receiving the Start Transmit packet.
Response:
Addresses in 64-byte mode/Addresses in 128-byte mode
Adrs.

Bit 7
Requests sending the configuration data configured via the network (i.e., RETURN
SETTING packet).
3bit Data of Bit2-0 on DATA0 in the RETURN SETTING packet, is selected by the “P”
option.
P=0 (CMD=01h) : Bit2-0 is all zero (Compatible with TMC20080)
P=1 (CMD=11h) : Bit2-0 is PGS2-0 which is I/O ports direction status
The RETURN SETTING packet is broadcasted upon receiving own token. (Refer to 2.2.3)
