(1) EP0_PID (Response PID) Bits (b15~b14)
These bits set the PID for response to the host at data/status stage of the control transfer.
At setup stage, the ACK response is executed irrespective of these bits.
Writing these bits are ignored when the VALID bit is equal to“1”.
When these bits are set to “00”
When these bits are set to “01”
<When set to control write transfer (ISEL bit = “0”)>
<When set to control read transfer (ISEL bit = “1”)>
When these bits are set to “1x”
The NAK response is not executed even if these bits are set to “00” when the data is being received at data
stage. The settings of these bits are reflected from the next transaction.
Similarly, the transmission is not interrupted even if these bits are set to “00” when the data is being
transmitted at data stage.
Further, these bits are automatically set to the values below when the following states occur:
2 0 0 4 . 1 1 . 0 1
When setup token is received
When the request set to automatic response (SET_ADDRESS or SET_CONFIGURATION) is received
When sequence error occurs (CTSQ bits are set to “110”)

The CCPL bit also is automatically set to “1” and transmits the zero-length packet at the succeeding
status stage (IN transaction).

In case the SIE side buffer is not ready to receive, the EPB_NRD bit is
set to “1” when OUT token is received.
In case the SIE side buffer is not ready to transmit, the EPB_NRD bit is
set to “1” when IN token is received.
In case the SIE side buffer is not ready to receive/transmit, the
EPB_NRD bit is set to “1” when OUT token is received.
