Peripheral CAN[edit | edit source]
The CAN interface available on AURA is based on i.MX93 SoC. The SOC includes two instances of CAN-FD Controllers (CAN-FD1 is in AONMIX and CAN-FD2 is in WAKEUPMIX).
The FlexCAN module is a full implementation of the CAN with Flexible Data Rate (CAN FD) protocol specification and CAN protocol specification, Version 2.0 B compliant with the ISO 11898-1:2015 standard
Description[edit | edit source]
The FlexCAN module includes these distinctive features:
- Flexible mailboxes configurable to store 0 to 8, 16, 32, or 64 bytes data length
- Each mailbox configurable as receive or transmit, all supporting standard and extended messages
- Individual Rx Mask registers per mailbox
- Full-featured
- legacy Rx FIFO with storage capacity for up to six frames and automatic internal pointer handling with DMA support
- enhanced Rx FIFO with storage capacity for up to 20 CAN FD frames
- Transmission abort capability
- Flexible message buffers (MBs), totaling 96 message buffers of 8 bytes data length each, configurable as Rx or Tx
- Programmable
- Loop-Back mode supporting self-test operation
- Programmable transmission priority scheme: lowest ID, lowest buffer number, or highest priority
- Time stamp based on 32-bit free running timer, with an optional external time tick
- Short latency time due to an arbitration scheme for high-priority messages
- Low power modes, with programmable wakeup on bus activity
- Powerful
- legacy Rx FIFO ID filtering, capable of matching incoming IDs against either 128 extended, 256 standard, or 512 partial (8 bit) IDs, with up to 32 individual masking capability
- Enhanced Rx FIFO ID filtering, capable of matching incoming IDs against either 64 extended or 128 standard ID filter elements with three filtering schemes: mask + filter, range, and two filters without mask
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
