MC33664 - Sleepmode

[Patrick_Pavle]

Dear Community,

how does the MC3377x know whether it has to send a wake-up sequence or not?

My MC33664 should be in sleep mode by default and only be active when messages are sent or received.

Can the MC3377x recognize when the transceiver is in sleep mode?

What happens to the message from the MC3377x if the MC33664 is not changed in normal mode in time?

BR, Patrick

Hi 

A wake-up pulse sequence can be generated by any slave node on the network by using
the same wake-up pulse sequence. below picture a wake-up generated by a slave
device on the network:

HI @guoweisun,

yes, but how does a slave know that it has to send a wake-up sequence?

And what happens to a message from the slave if the MC33664 is not set in normal mode in time?
