This register indicates the status of a channel with respect to USB- and AHB-related events. The
application must read this register when the Host Channels Interrupt bit of the Core Interrupt register
(GINTSTS.HChInt) is set. Before the application can read this register, it must first read the Host All
Channels Interrupt (HAINT) register to get the exact channel number for the Host Channel-n Interrupt
register. The application must clear the appropriate bit in this register to clear the corresponding bits in the
HAINT and GINTSTS registers.
