15.6 ISSUE 2.4 TO ISSUE 2.5

Section	Ref	Change
		Update document revision and redistribute

11.1		Change VCC to VDD.
11.2		Remove VCC

15.7 ISSUE 2.3 TO ISSUE 2.4

Section	Ref	Change
Title		Change from data sheet to user manual

Title		Add Atmel part number as a reference

3.2	External Ports	Add depth of external port FIFOs.

5.2	SpaceWire	Rename data strobe IOs so the naming is consistent in the
