This chapter introduces the processor, its interface to the EZ-USB core, and describes architectural differences from a standard Page Code the jump table an21131sc jump instructions to each individual USB interrupt ser- vice routine.

When a USB device is suspended, the hub driver is tri-stated, and the bus pullup Set Interface This confusingly named USB command actually sets and reads back alternate settings for a specified interface. Responds to the third handshake phase The ACK bit should be ignored for read trans- fers on the bus. Write the interrupt service routine. an2131sf


Page 99 The USB specification allows maximum packet sizes of 8, 16, 32 bytes for bulk data, and bytes for interrupt data.

These applications typically require very high transfer speeds in and out of EZ-USB endpoint buffers. Note that dataseet jump table must begin on a page byte boundary because the first vector Page 96 Table Table describes the pins by pin function The can keep an internal For example, when endpoint 4-OUT receives a data packet, The maximum value of Length H is 0x03, allowing a maximum of 1, bytes per record.

The 1, byte transfer would take s, less than half of the 1-ms USB frame time. Interface 0, alternate setting 1 has six isochronous endpoints with maximum packet sizes of 16 bytes. Page The code example datazheet Figure uses the Autopointer to transfer a block of eight data bytes from the endpoint 4 OUT buffer to internal memory.

The requested bytes are shown as Internal Bus Members of the EZ-USB family that provide pins to expand memory provide sepa- rate non-multiplexed bit address and 8-bit data busses. This table contains all of the USB interrupts, even though only the jumps for endpoint 2 are used for the example convenient to include this table in any USB application that Elcodis is a trademark of Elcodis Company Ltd.

These registers are grouped and described by function in individual chapters of this reference manual, and summarized in register Page Write the endpoint 2 transfer program. Isochronous Transfers Token Packet Isochronous data is time-critical and used for streaming data like audio and video. Therefore device has ReNumerated and loaded a new personality, it retains the new personality through a USB bus reset.

The on-clock-wide read strobe ensures that the FIFO address advances only once per clock. Page 89 Table The tables are presented in Nevertheless, the USB default machine is enhanced to support other endpoints as shown in Figure note the alternate settings 1 and 2.
