The SAF1761 supports all the transfers given in
Rev.
Each programmable FIFO can be independently configured using its Endpoint
MaxPacketSize register (R/W: 04h), but the total physical size of all enabled endpoints (IN
plus OUT), including set-up token buffer, control IN and control OUT, must not exceed
8192 bytes.
This register sets the endpoint type of the indexed endpoint: isochronous, bulk or
interrupt. It also serves to enable the endpoint and configure it for double buffering.
Automatic generation of an empty packet for a zero-length TX buffer can be disabled using
bit NOEMPKT. The register contains 2 bytes. See
reserved
Description
reserved
Number of Transactions: High-Speed (HS) mode only.
00 — One packet per microframe
01 — Two packets per microframe
10 — Three packets per microframe
11 — reserved
These bits are applicable only for isochronous or interrupt transactions.
FIFO Size: Sets the FIFO size, in bytes, for the indexed endpoint. Applies to both high-speed
and full-speed operations.
