1004
For OUT endpoints: an interrupt is sent when all banks are busy.
For IN endpoints: an interrupt is sent when all banks are free.
For OUT endpoints: send an Interrupt when a Short Packet has been received.
0 = Short Packet Interrupt is masked.
1 = Short Packet Interrupt is enabled.
For IN endpoints: a Short Packet transmission is guaranteed upon end of the DMA Transfer, thus signaling a BULK or
INTERRUPT end of transfer or an end of isochronous (micro-)frame data, but only if the UDPHS_DMACONTROLx
register END_B_EN and UDPHS_EPTCTLx register AUTO_VALID bits are also set.
