Section 6.2 says:

The integer x shall be converted to an octet string S of length k as follows.  The string S shall satisfy
                      k
                y =  SUM  2^(8(k-i)) Si .
                    i = 1

It should say:

The integer y shall be converted to an octet string S of length k as follows.  The string S shall satisfy
                      k
                y =  SUM  2^(8(k-i)) Si .
                    i = 1

Note that the conversion fails if y >= 2^(8*k).

Notes:

Typo corrected. The integer y can not be converted, if the octet string is to short.
