Figure 54. Force Wake-up
• Force wake-up, no cyclic sense function, LX cyclic
• Force wake-up period
• No force wake-up, cyclic sense function, LX cyclic
• Cyclic sense period
• Wake-up levels on LX
• Disable Force wake-up,LX cyclic
• Disable LX
• CAN sleep and CAN wake-up disable
note: can interface will enter sleep mode as soon as $53 is sent
• Bit NoStop=»1»: sleep mode is allowed
• SBC and CAN module go to sleep mode
it will sleep on the rising edge of CS
