Product data sheet
6.7.1 Mode control
6.7 CAN transceiver
The integrated high-speed CAN transceiver on the UJA1066 is an advanced ISO 11898-2
and ISO 11898-5 compliant transceiver. In addition to standard high-speed CAN
transceiver features, the UJA1066 transceiver provides the following:
The CAN transceiver controller supports four operating modes: Active mode, On-line
mode, On-line Listen mode and Off-line mode; see
Two dedicated CAN status bits (CANMD) in the Diagnosis register are provided to indicate
the operating mode.

•
Enhanced error handling and reporting of bus and RXD/TXD failures; these failures
are separately identified in the System Diagnosis register
Integrated autonomous control system for determining the mode of the CAN
transceiver
Ground shift detection with two selectable warning levels, to detect possible local
ground problems before the CAN communication is affected
On-line Listen mode with global wake-up message filter allows partial networking
Bus connections are truly floating when power is off
