ignores the bit sent during the ACK slot in the CAN frame acknowledge field to ensure proper reception
of its own message. Both transmit and receive interrupts are generated.
25.3.2.5
In listen-only mode, transmission is disabled, all error counters are frozen and the module operates in a
CAN error passive mode. Only messages acknowledged by another CAN station will be received. If
FlexCAN detects a message that has not been acknowledged, it will flag a BIT0 error (without changing
the REC), as if it was trying to acknowledge the message. Because the module does not influence the CAN
bus in this mode, the device is capable of functioning like a monitor or for automatic bit-rate detection.
25.4
Each FlexCAN module has two I/O signals connected to the external MPU pins: CAN0TX, CAN0RX,
CAN1TX, and CAN1RX. CAN n TX transmits serial data to the CAN bus transceiver, while CAN n RX
receives serial data from the CAN bus transceiver.
25.5
The FlexCAN module address space is split into 128 bytes starting at the base address, and then an extra
512 bytes starting at the base address +128. The upper 512 are fully used for the message buffer structures,
as described in
occupied by various registers.
