Table 91. Priority Levels
As shown in Figure 71, many events can produce a USB interrupt:
•
•
•
•
•
•
•
•
TXCMPL: Transmitted In Data (see Table 98 on page 141). This bit is set by
hardware when the Host accept a In packet.
RXOUTB0: Received Out Data Bank 0 (see Table 98 on page 141). This bit is set
by hardware when an Out packet is accepted by the endpoint and stored in bank 0.
RXOUTB1: Received Out Data Bank 1 (only for Ping-pong endpoints) (see Table 98
on page 141). This bit is set by hardware when an Out packet is accepted by the
endpoint and stored in bank 1.
RXSETUP: Received Setup (see Table 98 on page 141). This bit is set by hardware
when an SETUP packet is accepted by the endpoint.
STLCRC: STALLED (only for Control, Bulk and Interrupt endpoints) (see Table 98
on page 141). This bit is set by hardware when a STALL handshake has been sent
as requested by STALLRQ, and is reset by hardware when a SETUP packet is
received.
SOFINT: Start of Frame Interrupt (See “USBIEN Register USBIEN (S:BEh) USB
Global Interrupt Enable Register” on page 138.). This bit is set by hardware when a
USB Start of Frame packet has been received.
WUPCPU: Wake-Up CPU Interrupt (See “USBIEN Register USBIEN (S:BEh) USB
Global Interrupt Enable Register” on page 138.). This bit is set by hardware when a
USB resume is detected on the USB bus, after a SUSPEND state.
SPINT: Suspend Interrupt (See “USBIEN Register USBIEN (S:BEh) USB Global
Interrupt Enable Register” on page 138.). This bit is set by hardware when a USB
suspend is detected on the USB bus.
