+                                 ;* Z have been assigned names XL - ZH. Highest RAM address for Internal

+                                 ;* The Register names are represented by their hexadecimal address.
+                                 ;* 
+                                 ;* The Register Bit names are represented by their bit number (0-7).

+                                 ;* Please observe the difference in using the bit names with instructions
+                                 ;* such as "sbr"/"cbr" (set/clear bit in register) and "sbrs"/"sbrc"

+RESOURCE USE INFORMATION
+------------------------
+
+Notice:
+The register and instruction counts are symbol table hit counts,
+and hence implicitly used resources are not counted, eg, the
+'lpm' instruction without operands implicitly uses r0 and z,
+none of which are counted.
+
+x,y,z are separate entities in the symbol table and are
+counted separately from r26..r31 here.
+
+.dseg memory usage only counts static data declared with .byte
