Idle

Idle time

CRC disabled:

The idle bit time is based on the

bit time calculated using the

start bits based on the last edge

of previous message to 1st

rising edge (start bit) of new

message If an error is detected

then the device shall default to

1.5 times the maximum

frequency (minimum bit time).

No idle time required after

enabling channel
