Protocol Control Command Write Busy — This status bit indicates the acceptance of the protocol control
command issued by the application via the POCCMD field. The FlexRay module sets this status bit when the
application has issued a protocol control command via the POCCMD field. The FlexRay module clears this
status bit when protocol control command was accepted by the PE.When the application issues a protocol
control command while the BSY bit is asserted, the FlexRay module ignores this command, sets the protocol
command ignored error flag PCMI_EF in the
of the POCCMD field.
0 Command write idle, command accepted and ready to receive new protocol command.
1 Command write busy, command not yet accepted, not ready to receive new protocol command.
Write Mode Command — This bit controls the write mode of the POCCMD field.
0 Write to POCCMD field on register write.
1 Do not write to POCCMD field on register write.
Protocol Control Command — The application writes to this field to issue a protocol control command to the
PE. The FlexRay module sends the protocol command to the PE immediately. While the transfer is running, the
BSY bit is set.
