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)
