Page The 1, byte transfer would take s, less than half of the 1-ms USB frame time. The USB specification allows maximum packet sizes of 8, 16, 32 bytes for bulk data, and bytes for interrupt data. The added SFR regis- ters and bits are summarized in Table Page 19 This chapter introduces some key USB concepts and terminology that should make read- ing the rest of this Technical Reference Manual easier.
The second strobe  is An optional DATA stage contains more data, if required. Time of delivery is the most important requirement for isochronous data.
Only one configuration is active at any time. Put it anywhere in memory and the jump table in step 1 will automatically jump to it. Sixteen addressable data registers hold data from the eight isochronous IN endpoints and the eight isochronous OUT endpoints. Suspend No USB activity for 3 msec. If still faster time is required, the routine can be modified to put more of the MOVX Page Code the jump table an231sc jump instructions to each individual USB interrupt ser- vice routine.
The function address is datasheeg to zero SOF Interrupt Figure Bulk endpoints use maximum packet sizes and therefore buffer sizes 16, 32 bytes. Page 95 Table Page 74 Table Set Interface This confusingly named USB command actually sets and reads back alternate settings for a specified interface.

The requested bytes are shown as First, as described in this chapter, it manages the serial EEPROM interface that operates automatically at power-on to deter- mine the enumeration Page 40 Table Page 56 Figure Therefore device has ReNumerated and loaded a new personality, it retains the new personality through a USB bus reset.
Page EP0-IN such information as what device driver to load, how many endpoints it has, its different configurations, alternate settings it may use, and informative text strings about the device.
I2C Controller describes how the boot load Power control is accomplished using a combination of Page Write the INT2 interrupt vector. The registers are named according to the following conventions. Page 45 Table Referring to the logic inside the dotted lines, each USB interrupt source has an interrupt request latch.
This chapter introduces the processor, its interface to the EZ-USB core, and describes architectural differences from a standard Page 11 Vatasheet Page Isochronous Transfer Speed The amount of data USB can transfer during a 1-ms frame is slightly more than 1, bytes per frame 1, bytes theoretical, without accounting for USB overhead and bus utilization.

SFRs The EZ-USB family was designed to keep coding as standard as possible, to allow easy integration of catasheet software development tools. Table describes the pins by pin function Write the INT2 interrupt vector. Isochronous Transfers Token Packet Isochronous data is time-critical and used for streaming data like audio and video.

The code at lines fills the an21131sc 2-IN buffer with 64 bytes of a decrementing count. Added Registers and Bits Page 89 Table Page 34 Variants There are two pin devices:
