DESCRIPTION

BIT

R/W

Set to “1” if a SET_FEATURE_ENDPOINT_HALT command

is received on any endpoint by the SIE. Which endpoint is

STALLed can be determined by examining their CTL

registers.

Set to “1” if a CLEAR_FEATURE_ENDPOINT_HALT

command is received on any endpoint by the SIE. Which

endpoint’s STALL condition is cleared can be determined

by examining their CTL registers.

Set to “1” if a SET_CONFIGURATION command is received

on endpoint 0 by the SIE and the resulting configuration is

set and reported in the USB_CONFIG register.

This read only bit always returns the value of “0”.

Set to “1” if a SET_INTERFACE command is received on

endpoint 0 by the SIE.

This read only bit always returns the value of “0”.

Set to “1” if a SET_FEATURE_REMOTE_WAKE_UP
