4.3.9 IEPBCTX_n: Input Endpoint X-Byte Count (n = 1 to 3) (Offset 2)

BIT NAME RESET FUNCTION
6−0 C[6:0] x X-Buffer byte count:
X000.0000b Count = 0
X000.0001b Count = 1 byte
:
:
X011.1111b Count = 63 bytes
X100.0000b Count = 64 bytes
Any value ≥ 100.0001b may result in unpredictable results.
7 NAK x NAK = 0
NAK = 1
Buffer contains a valid packet for host-IN transaction
Buffer is empty (gives NAK response to host-IN request)
4.3.10 IEPBBAY_n: Input Endpoint Y-Buffer Base Address (n = 1 to 3) (Offset 5)
765 4 32 1 0
A10 A9 A8 A7 A6 A5 A4 A3
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 Y-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.
4.3.11 IEPBCTY_n: Input Endpoint Y-Byte Count (n = 1 to 3) (Offset 6)
765 4 32 1 0
NAK C6 C5 C4 C3 C2 C1 C0
