@@ -15,11 +15,11 @@ Overview
TWAI is a highly reliable, multi-master, real-time, serial asynchronous communication protocol designed for automotive and industrial applications. It is compatible with the frame structure defined in the ISO 11898-1 standard and supports both standard frames with 11-bit identifiers and extended frames with 29-bit identifiers. The protocol supports message prioritization with lossless arbitration, automatic retransmission, and fault confinement mechanisms. The {IDF_TARGET_NAME} includes {IDF_TARGET_CONFIG_SOC_TWAI_CONTROLLER_NUM} TWAI controllers, allowing for the creation of {IDF_TARGET_CONFIG_SOC_TWAI_CONTROLLER_NUM} driver instances.
.. only:: SOC_TWAI_SUPPORT_FD
.. only:: SOC_TWAI_FD_SUPPORTED
The TWAI controllers on the {IDF_TARGET_NAME} also compatible with FD format (a.k.a. CAN FD) frames defined in ISO 11898-1, and can transmit and receive both classic and FD format frames.
.. only:: not SOC_TWAI_SUPPORT_FD
.. only:: not SOC_TWAI_FD_SUPPORTED
The TWAI controllers on the {IDF_TARGET_NAME} are **not compatible with FD format frames and will interpret such frames as errors.**
