USB Interrupt Control System
As shown in Figure 21-16, many events can produce a USB interrupt:
• TXCMPL: Transmitted In Data (see
• RXOUTB0: Received Out Data Bank 0 (see
• RXOUTB1: Received Out Data Bank 1 (only for Ping-pong endpoints) (see
• RXSETUP: Received Setup (see
• STLCRC: STALLED (only for Control, Bulk and Interrupt endpoints) (see
• SOFINT: Start of Frame Interrupt
• WUPCPU: Wake-Up CPU Interrupt
• SPINT: Suspend Interrupt
