recognized for 2.5 μs or longer. In High-Speed operation, the flag is asserted when SE0
was recognized for 3 ms or longer, after determining whether USB_RESET or
suspended state. Then, after UDC2 has driven Chirp-K for about 1.5 ms the flag will be
deasserted when either one of the following states was recognized:
interrupt is recognized, the software should read the Setup-Data storage register (8
bytes) to make judgment of request. This interrupt will be deasserted by writing 1 into
the relevant bit (bit 0) of INT register. INT register should be cleared at the point the
interrupt was recognized.
packets while UDC2 is processing the DATA-Stage (before issuing the “Setup_Fin”
command), UDC2 will return “NAK” and asserts this flag to “H”. When this interrupt
is recognized, the software should issue the “Setup_Fin” command from the Command
register to make the STATUS-Stage of UDC2 end. This interrupt will be deasserted by
writing 1 into the relevant bit (bit 1) of INT register. INT register should be cleared at
the point the interrupt was recognized.
interrupt will be deasserted by writing 1 into the relevant bit (bit 2) of INT register.
INT register should be cleared at the point the interrupt was recognized.
received (when the transaction finished normally). This interrupt will be deasserted by
writing 1 into the relevant bit (bit 5) of INT register. INT register should be cleared at
the point the interrupt was recognized.
