For non-control pipe, this field indicates the number of the current bank.
This field may be updated 1 clock cycle after the RWALL bit changes, so the user should not poll this field for an interrupt.
This field indicates the number of busy bank.
For OUT pipe, this field indicates the number of busy bank(s), filled by the user, ready for OUT transfer. When all banks are
busy, this triggers an PnINT interrupt if UPCONn.NBUSYBKE is one.
For IN pipe, this field indicates the number of busy bank(s) filled by IN transaction from the Device. When all banks are free, this
triggers an PnINT interrupt if UPCONn.NBUSYBKE is one.
This bit is cleared when the RAMACERIC bit is written to one.
This bit is set when a RAM access underflow error occurs during IN data stage.
