ICR register description
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.
Set by software to enable an interrupt request whenever a message has been
received free of errors.
Cleared by software to disable receive interrupt requests.
Set by software to enable an interrupt request whenever a message has been
successfully transmitted.
Cleared by software to disable transmit interrupt requests.
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 interrupt requests.
Set by software to enable an interrupt request whenever a message should be stored
and no receive buffer is available.
Cleared by software to disable overrun interrupt requests.
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 interrupts.
