• CAN sleep and CAN wake-up enable
note: CAN interface will enter sleep mode as soon as this command is sent in
• X is the slew rate.(ex:$56 for slew rate 3).
note: default slew rate is slew rate 0 (the minus one).
• no force wake-up, no cyclic sense, no LX cyclic
• Wake-up levels on LX
refer to the specification for details
• Can go to sleep and wake-up enable
• Can go to sleep and wake-up disable
• Turn off HS1
• Turn on HS1
