This output will always be a hexadecimal representation which must be converted to binary format. In this example, the conversion gives 
00000000000010110010000011111111 in binary format, see Appendix H, Page 236 for a complete conversion list. Reading from right to left 
you can look to see what each bit represents in Table D-5, following.
