KNOWN ISSUES AND LIMITATIONS
----------------------------
	
	1.) Firmware works with the Silicon Labs IDE v1.71 or later and the 
	Keil C51 tool chain. Project and code modifications will be 
	necessary for use with different tool chains.

	2.) Compiler optimization emphasis is selected as "favor small code". 
	This selection is necessary for the project to be compiled with the 
	trial version of the Keil C51 Compiler (under 4k code space).

	3.) If using the C8051F320TB target board, jumper J2 should be 
	installed if the board is wall-powered; 
	jumper J11 should be installed if bus-powered.

	4.) Windows application and driver supports Win2K, XP, and 98 only.
