load .mif-file on DE0-CV board

and here is my mif-file:

DEPTH = 64;             % Memory depth and width are required %
WIDTH = 6;              % Enter a decimal number %
ADDRESS_RADIX = HEX; % Address and value radixes are optional %
DATA_RADIX = HEX;     % Enter BIN, DEC, HEX, or OCT; unless %
CONTENT
BEGIN
     : 0000; % Range--Every address from 00 to 3F = 0000 %
    00 : 0x22;
    01    : 000011;
    02    : 22;
    03    : 0x22;
    04    : 0x22;
    05    : 0x22;
END ;

I just want to change some of the memory blocks for testing reasons. Because I'm not sure how i write it correctly I tried different possibilities.

The memory is a 64 x 6-bit memory. So do I have to write

000001

or "000001"

or 1

or '1'

or 0x1

or "0x1" for e.g. a value of 1?
