NAME RESET FUNCTION
6−0 S[6:0] x X- and Y-buffer size:
0000.0000b Size = 0
0000.0001b Size = 1 byte

:
0011.1111b Size = 63 bytes
0100.0000b Size = 64 bytes
Any value ≥ 100.0001b may result in unpredictable results.

FF58h)

BIT
NAME RESET FUNCTION
1−0 RSV x Reserved = 0
2 USBIE x USB interrupt enable on transaction completion
USBIE = 0 No interrupt on transaction completion
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, then 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
4.3.8 IEPBBAX_n: Input Endpoint X-Buffer Base Address (n = 1 to 3) (Offset 1)

R/W R/W R/W R/W R/W R/W R/W R/W
BIT
NAME RESET FUNCTION
7−0 A[10:3] x A[10:3] of X-buffer base address (padded with 3 LSBs 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.
