ISP1583
Hi-Speed USB peripheral controller
The ISP1583 supports all the transfers given in Ref. 1 “Universal Serial Bus Specication
Each programmable FIFO can be independently congured 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.
9.3.7 Endpoint Type register (address: 08h)
This register sets the endpoint type of the indexed endpoint: isochronous, bulk or
interrupt. It also serves to enable the endpoint and congure 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, and the bit allocation is shown in Table 47.
