CONTROLLER AREA NETWORK (Cont’d)
INTERRUPT CONTROL REGISTER (ICR)
Read/Write
Reset Value: 00h
Bit 6 = ESCI
Extended Status Change Interrupt
Read/Set/Clear
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.
Bit 5 = RXIE
Receive Interrupt Enable
Read/Set/Clear
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.
Bit 4 = TXIE
Transmit Interrupt Enable
Read/Set/Clear
Set by software to enable an interrupt request
whenever a message has been successfully trans-
mitted.
Cleared by software to disable transmit interrupt
requests.
Bit 3 = SCIE
Status Change Interrupt Enable
Read/Set/Clear
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.
Bit 2 = ORIE
Overrun Interrupt Enable
Read/Set/Clear
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.
Bit 1 = TEIE
Transmit Error Interrupt Enable
Read/Set/Clear
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.
Bit 0 = ETX
Early Transmit Interrupt
Read/Set/Clear
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.
