+STK500 Commands **preliminary information**
+---------------
+
+Extracted by Jason Kyle 20010701
+Updated 200201
+
+The latest version of this document can be found at www.avr1.org.
+
+Notes:
+- Incomplete but sufficient to make progress on free tools.
+- All commands are terminated by 0x20
+- All successful responses are framed 0x14 data 0x10 (i.e. NULL response is
+ 0x14 0x10)
+- Commands invalid in current mode (i.e not in pgm mode, pgm page) give
+ 0x14 0x13 response.

+
+Normally memory is programmed or read in 0x0100 byte chunks, obviously if a
+program doesn't align to an 0x0100 length then there will be a < 0x0100 chunk
+at the end.
+
+
+Writing mega163. Set address to 0x0000, write 0x0100 bytes, set address to
+0x0080, write 0x0100 bytes etc... STK500 must auto detect end of page boundry
+and write current page to address specified in last setaddress cmd.
