6.1 Operating configurations
The block diagram of the total transceiver is illustrated in
In node configuration the transceiver operates as a stand-alone transceiver.
The transceiver can be configured as node by connecting pins TRXD0 and TRXD1 to
ground during a power-on situation (PWON flag is set). The configuration will be latched
when the PWON flag is reset, see
The following operating modes are available:
In star configuration the transceiver operates as a branch of a FlexRay active star.
The transceiver can be configured as star by connecting pin TRXD0 or TRXD1 to V
during a PWON situation (PWON flag is set). The configuration will be latched when the
PWON flag is reset, see
It is possible to redirect data from one branch to other branches via the inner bus. It is also
possible to send data to all branches via pin TXD, if pins TXEN and BGE have the correct
polarity.
The following operating modes are available:
In the star configuration all modes are autonomously controlled by the transceiver, except
in the case of a wake-up.
