ENUM MTU3_G_EP0_STATE(9)

💖 NAME 💖

okay so bestie, this is the enum mtu3_g_ep0_state(9) page from the Kernel API Manual, and it’s literally all about endpoint 0 states — the ep0 enum situation, no cap. 💅✨

✨ SYNOPSIS ✨

Here’s the enum exactly as it appears, because we do not play games with code:

       enum mtu3_g_ep0_state {
           MU3D_EP0_STATE_SETUP ,
           MU3D_EP0_STATE_TX ,
           MU3D_EP0_STATE_RX ,
           MU3D_EP0_STATE_TX_END ,
           MU3D_EP0_STATE_STALL

       };

🎀 Constants 🎀

• MU3D_EP0_STATE_SETUP — this one is waiting for SETUP, or it received a SETUP without a data stage. iconic waiting-room energy. 🫶
• MU3D_EP0_STATE_TX — the IN data stage. periodt. 💅
• MU3D_EP0_STATE_RX — the OUT data stage. slay. 🌸
• MU3D_EP0_STATE_TX_END — the last IN data is transferred, and now it’s waiting for its completion interrupt. highkey suspenseful. 😭
• MU3D_EP0_STATE_STALL — ep0 is in stall status, and it will be auto-cleared after it receives a SETUP. not forever, bestie. 💀
