x
USB interrupt enable on transaction completion
USBIE = 0 No interrupt
USBIE = 1 Interrupt on transaction completion
3
STALL
0
USB stall condition indication. Set by the UBM but can be set/cleared by the MCU
STALL = 0 No stall
STALL = 1 USB stall condition. If set by the MCU a STALL handshake is initiated and the bit is cleared
automatically.
4
DBUF
x
Double buffer enable
DBUF = 0 Primary buffer only (X-buffer only)
DBUF = 1 Toggle bit selects buffer
5
TOGLE
x
USB toggle bit. This bit reflects the toggle sequence bit of DATA0, DATA1
6
ISO
x
ISO = 0 Nonisochronous transfer. This bit must be cleared by the MCU since only nonisochronous
transfer is supported
7
UBME
x
UBM enable/disable bit. Set/cleared by the MCU
UBME = 0 UBM cannot use this endpoint
UBME = 1 UBM can use this endpoint

A[10:3]
x
A[10:3] of X-buffer base address (padded with 3 LSB of zeros for a total of 11 bits). This value is set by the
MCU. The UBM or DMA uses this value as the start-address of a given transaction, but note that the UBM
or DMA does not
change this value at the end of a transaction.
