This register is used to identify the exact interrupt event. When the external controller receives an interrupt, it
should first read this register to check the interrupt event. Writing ‘1’ to clear the individual interrupt bit.
DATATX -
The endp1 transmits a data packet completely
DATARX -
The endp2 receives a data packet
EP3TX
-
Endp3 transaction is detected
EPPINT - This bit means external EPP interrupt is detected.
The EPPTXEN/EPPRXEN is cleared by hardware when this bit is set.
SUSPND -
USB suspend request is detected.
RESUME -
USB resume request is detected.
