CR16CAN has access to one interrupt vector in the CR16
CPU. The interrupt process can be initiated from the follow-
ing sources.
CAN data transfer
— Reception of a valid data frame in the buffer. (Buffer
state changes from RX_READY to RX_FULL or
RX_OVERRUN).
— Successful transmission of a data frame. (Buffer state
changes from TX_ONCE to TX_NOT_ACTIVE or
RX_READY)
INTERRUPTS
— Successful response to a remote frame. (Buffer state
changes from TX_ONCE_RTR to TX_RTR).
— Transmit scheduling. (Buffer state changes from
TX_RTR to TX_ONCE_RTR).
CAN error conditions is the detection of an CAN error.
(The CEIPND bit in the CIPND register will be set as well
as the corresponding bits in the error diagnostic register
CEDIAG).
The receive/transmit interrupt access to every message buff-
er can be individually enabled/disabled in the CIEN register.
The pending flags of the message buffer are located in the
Figure 66.
