4.12.3
A separate 8-byte buffer at 0xE6B8-0xE6BF holds the Setup
data from a CONTROL transfer.
4.12.4
Endpoints 0 and 1 are the same for every configuration.
Endpoint 0 is the only CONTROL endpoint, and endpoint 1 can
be either BULK or INTERRUPT. The endpoint buffers can be
configured in any 1 of the 12 configurations shown in the
vertical columns. In full-speed, BULK mode uses only the first
64 bytes of each buffer, even though memory exists for the
allocation of the isochronous transfers in BULK mode the
unused endpoint buffer space is not available for other opera-
tions. An example endpoint configuration would be:
EP2—1023 double buffered; EP6—64 quad buffered (column 8).

Notes:
• 3 × 64 bytes
• 8 × 512 bytes (Endpoints 2, 4, 6, 8)
• EP0—Bidirectional endpoint zero, 64-byte buffer
• EP1IN, EP1OUT—64-byte buffers, bulk or interrupt
• EP2,4,6,8—Eight 512-byte buffers, bulk, interrupt, or isoch-

ronous, of which only the transfer size is available.
EP4 and EP8 can be double buffered, while EP2 and 6 can
be either double, triple, or quad buffered. Regardless of the
physical size of the buffer, each endpoint buffer accommo-
dates only one full-speed packet. For bulk endpoints the
maximum number of bytes it can accommodate is 64, even
though the physical buffer size is 512 or 1024. For an
ISOCHRONOUS endpoint the maximum number of bytes
it can accommodate is 1023. For endpoint configuration
options, see Figure 4-5.
“0” means “not implemented.”
“2×” means “double buffered.”

4.13.1
The FX1 slave FIFO architecture has eight 512-byte blocks in
the endpoint RAM that directly serve as FIFO memories, and
are controlled by FIFO control signals (such as IFCLK, SLCS#,
SLRD, SLWR, SLOE, PKTEND, and flags). The usable size of
these buffers depend on the USB transfer mode as described
in Section 4.12.2.
In operation, some of the eight RAM blocks fill or empty from
the SIE, while the others are connected to the I/O transfer
logic. The transfer logic takes two forms, the GPIF for internally
generated control signals, or the slave FIFO interface for
externally controlled transfers.
4.13.2
The FX1 endpoint FIFOS are implemented as eight physically
distinct 256x16 RAM blocks. The 8051/SIE can switch any of
the RAM blocks between two domains, the USB (SIE) domain
and the 8051-I/O Unit domain. This switching is done virtually
