B−itR6e=adE/SSCetI/CElxetaernded Status Change Interrupt
Set by software to specify that SCIF is to be set on
receive errors also.
Cleared by software to set SCIF only on status
changes and wake-up but not on all receive errors.
B−itR5e=adR/SXeIEt/CRleecaerive Interrupt Enable
Set by software to enable an interrupt request
whenever a message has been received free of er-
rors.
Cleared by software to disable receive interrupt re-
quests.
B−itR4e=adT/XSIeEt/TCrlaenasr mit Interrupt Enable
Set by software to enable an interrupt request
whenever a message has been successfully trans-
mitted.
Cleared by software to disable transmit interrupt
requests.
B−itR3e=adS/CSIeEt/CSlteaaturs Change Interrupt Enable
Set by software to enable an interrupt request
whenever the node’s status changes in run mode or
whenever a dominant pulse is received in standby
mode.
Cleared by software to disable status change inter-
rupt requests.
B−itR2e=adO/SReIEt/COlevearrrun Interrupt Enable
Set by software to enable an interrupt request
whenever a message should be stored and no re-
ceive buffer is avalaible.
Cleared by software to disable overrun interrupt re-
quests.
B−itR1e=adT/ESIeEt/TCrlaenasr mit Error Interrupt Enable
Set by software to enable an interrupt whenever an
error has been detected during transmission of a
message.
Cleared by software to disable transmit error inter-
rupts.
B−itR0e=adE/TSXetE/CalrelyarTransmit Interrupt
Set by software to request the transmit interrupt to
occur as soon as the arbitration phase has been
passed successfully.
Cleared by software to request the transmit inter-
rupt to occur at the completion of the transfer.
