george is correct 1 more bit
if u are using an assembler like dscope.
then you can initialise 0x11 to some variable like this
LOCATION: EQU 011H
in your program you can use the word LOCATION to access the location 0x11 it is always easy to remember the name rather than the location

sample assembler program using DSCOPE
-------------------------------------
LOCATION: EQU 0011H
ORG 0000H
JMP START

START:
MOV LOCATION,#0FH
RET
THATS IT BYE FROM Srikanth
