ENUM ES58X_FD_CTRLMODE(9)

💖 NAME 💖

okay so bestie, this page is from the Kernel API Manual, and it’s about enum es58x_fd_ctrlmode — Controller mode. That’s the whole assignment: the controller mode enum. periodt. 💅

📜 SYNOPSIS 📜

here’s the exact lineup, no cap: ✨

       enum es58x_fd_ctrlmode {
           ES58X_FD_CTRLMODE_ACTIVE ,
           ES58X_FD_CTRLMODE_PASSIVE ,
           ES58X_FD_CTRLMODE_FD ,
           ES58X_FD_CTRLMODE_FD_NON_ISO ,
           ES58X_FD_CTRLMODE_DISABLE_PROTOCOL_EXCEPTION_HANDLING ,
           ES58X_FD_CTRLMODE_EDGE_FILTER_DURING_BUS_INTEGRATION

       };

✨ Constants ✨

every constant is a little vibe, and every single one matters, fr fr:

• ES58X_FD_CTRLMODE_ACTIVE — send and receive messages. 💖
• ES58X_FD_CTRLMODE_PASSIVE — only receive messages (monitor). Do not send anything, not even the acknowledgment bit. 👀
• ES58X_FD_CTRLMODE_FD — CAN FD according to ISO11898-1. 🦋
• ES58X_FD_CTRLMODE_FD_NON_ISO — follow Bosch CAN FD Specification V1.0. 🌸
• ES58X_FD_CTRLMODE_DISABLE_PROTOCOL_EXCEPTION_HANDLING — How to behave when CAN FD reserved bit is monitored as dominant. (c.f. ISO 11898-1:2015, section 10.4.2.4 "Control field", paragraph "r0 bit"). 0 (not disable = enable): send error frame. 1 (disable): goes into bus integration mode (c.f. below). 😭
• ES58X_FD_CTRLMODE_EDGE_FILTER_DURING_BUS_INTEGRATION — 0: Edge filtering is disabled. 1: Edge filtering is enabled. Two consecutive dominant bits required to detect an edge for hard synchronization. 🔥
