0 = BUSY_BANK Interrupt is masked.

1 = BUSY_BANK Interrupt is enabled.

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 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.
