EPi_PID
These bits set the PID to be responded to the host.
These bits are valid only when the transfer type is set to bulk transfer mode or interrupt transfer mode
(EPi_TYP bits = “01” or “10”). Set these bits to “01” at isochronous transfer mode (EPi_TYP bits = “11”).
When these bits are set to “00”, the NAK response is executed, regardless of the buffer state.
When these bits are set to “01”;
<When set to OUT buffer (EPi_DIR bit = “0”)>
<When set to IN buffer (EPi_DIR bit = “1”)>
When these bits are set to “1x”, the STALL response is executed, regardless of the buffer state.
When set to OUT buffer, if a data exceeding the maximum packet size is received, regardless of these bit
values, these bits are set automatically to “1x” (STALL).

ACK response after receiving the data with the SIE side buffer in the receive ready state.
NAK response with the SIE side buffer in the receive not ready state.
Transmits the data with the SIE side buffer in transmit ready state.

When the SIE side buffer is not in receive ready state, if the OUT token is received, the
EPB_NRD bit is set to “1”.
When the SIE side buffer is in the transmit not ready state, if the IN token is received, the
EPB_NRD bit is set to “1”.
