(when the transaction finished normally). In that case, which endpoint the transfer
was made can be identified by checking INT_EP register. This interrupt will be
deasserted by writing 1 into the relevant bit (bit 6) of INT register, or by writing 1 into
all bits set in INT_EP register. INT register should be cleared at the point the interrupt
was recognized.
“H” is asserted only when Zero-Length data is received in the DATA-Stage. It will not
be asserted when Zero-Length data is received in the STATUS-Stage. Which endpoint
has received the data can be identified by reading the bits [11:8] of Command register
or checking INT_RX_DATA0 register. This interrupt will be deasserted by writing 1
into the relevant bit (bit 3) of INT register, or by writing 1 into all bits set in
INT_RX_DATA0 register. INT_RX_DATA0 register should be cleared at the point the
interrupt was recognized.
into the relevant bit (bit 4) of INT register. INT register should be cleared at the point
the interrupt was recognized.

case, which endpoint has transmitted the NAK can be identified by checking INT_NAK
register. This interrupt will be deasserted by writing 1 into the relevant bit (bit 7) of
INT register, or by writing 1 into all bits set in INT_NAK register. By default, this flag
will not be asserted when NAK was transmitted. Therefore, you should write 0 into
the relevant endpoint of INT_NAK_MASK register to release the mask in order to use
this flag.
