;
; A Simple isochronous transfer.  Reads 8051 ports A,B and C, and
; continuously sends a five byte packet over EP8IN:  
;
; Byte0:	Frame Count H
; Byte1:	Frame Count L
; Byte2:	PORTA pins
; Byte3:	PORTB pins
; Byte4:	PORTC pins
;
; You can observe and study USB Isochronous transfers using this code with
; the Using the EZ-USB development board with the Anchor Control Panel.
; The code illustrates how to transport IO PORT data to the isochronous
; endpoint buffer EP8IN.  For simplicity the interrupt system is not used,
; instead the SOF (Start of Frame) bit is polled to detect the arrival of 
; and SOF token.
;
; To use with the Anchor Control Panel:
; 1. Download 'eziso.hex'.  
; 2. Press "SetIFace" to select Interface=0, AltSetting=1
;    On the Iso Trans bar, set: 
;	 Pipe to '7:Endpoint 8 IN'
;    Packets(PktCount)=1
;	 PktSize=5
; 	 BuffCount=1
;	 FrmPerBuff=1
;
; Then click the 'Iso Trans' button as many times as you wish.  The frame
; count and all 24 input port lines appear in the data window.
