CAN_INT
CAN_INT
read-only (87C196CA)
The CAN interrupt pending (CAN_INT) register indicates the source of the highest priority pending
interrupt. If a status change generated the interrupt request, software can read the status register
(CAN_STAT) to determine whether the interrupt request was caused by an abnormal error rate, a
successful reception, a successful transmission, or a new error. If an individual message object
generated the interrupt request, software can read the associated message object control 0 register
(CAN_MSG x CON0). The INT_PND bit-pair will be set, indicating that a receive or transmit interrupt
request is pending.
