If a pipe is under the conditions below, this module sets the corresponding bit in BEMPSTS to 1.
In this case, this module generates a BEMP interrupt if software sets the PIPEBEMPE bit in
BEMPENB corresponding to the corresponding pipe and the BEMPE bit in INTENB0 to 1. If
software clears all the bits in BEMPSTS, this module clears the BEMP bit in INTSTS0.
1. When the transmitting direction (writing to the buffer memory) has been set
2. When the receiving direction (reading from the buffer memory) has been set
Figure 23.5 shows the timing at which a BEMP interrupt is generated when the function controller
function has been selected.

When all of the data stored in the buffer memory has been transmitted
If the buffer memory is being used as a double buffer, however, the following conditions
should be met.
⎯ A BEMP interrupt is generated if the buffer on one side is empty and transmitting of data
⎯ A BEMP interrupt is generated if data consisting of less than eight bytes is being written to
If the size of the data packet that was received exceeded the maximum packet size and the
maximum packet size is not set to 0 (MXPS ≠ 0), this module sets the PID bit of the
corresponding pipe to STALL.
