end of
Power-on-reset
P82C150 receives 1st message
(any message)
P82C150 receives 2nd message
(any message), acknowledge not
required but no active error flag allowed
P82C150 waits until bus-off recovery
sequence finished
P82C150 sends 'sign-on' message
MHA080
P82C150 receives calibration
message within 8192 bit times after
wake-up or bus mode change
P82C150 is roughly calibrated and has
started bus-off recovery sequence
(counting 129 blocks of 11 recessive bits)
21
Communication with host node possible
P82C150 is on bus and ready to
send after bus-of f sequence finished
Rough calibration verified
P82C150 is fine calibrated
I/O registers cleared
and I/O register cleared
bus mode change e.g. due to
missing reception of a calibration
message within 8192 bit times
