ONTROL REGISTER
This register has write access only in Normal and Standby modes; it allows the CAN and the LIN physical layer to be
configured.

reserved for future use; should always be set to logic 0 in
order to secure compatibility with future functions which will
be activated by a logic 1
allows Selective Sleep state to be entered; cleared
whenever the UJA1061 enters On-line or Active mode
no Selective Sleep mode allowed (default)
256 ms time until CAN falls into Off-line (400 ms after
Wake-up)
64 ms time until CAN falls into Off-line (400 ms after
Wake-up)
CAN transmitter is disabled; allows setting ‘listen only’
behaviour; set also due to a detected short at V2 or a
RXDC recessive or TXDC dominant clamping failure
CAN transmitter is enabled
TXD signal is forwarded to RXD during CAN
transmitter OFF
TXD signal is not forwarded to RXD during CAN
transmitter OFF
