Interrupt pre message buffer that
designates that a transmission
or reception was successful.
TouCAN module has entered the
bus off state.
Toucan detects an transmit or
receive error. Other bits in the
ESTAT register give further
information on the error type.
Transition on CAN bus has
caused the TouCAN module to
wake-up
