Section 6.1 says:

   The filling of N1 and N2 is encrypted in the electronic codebook mode
   according to the requirements of section 5.1.  The resulting
   encrypted filling of N1 and N2 is the second 64-bit block of the
   running key Gc(2); this block is bitwise added modulo 2 in the adder
   CM5 with the first 64-bit block of the plain text Tp(2).  

It should say:

   The filling of N1 and N2 is encrypted in the electronic codebook mode
   according to the requirements of section 5.1.  The resulting
   encrypted filling of N1 and N2 is the second 64-bit block of the
   running key Gc(2); this block is bitwise added modulo 2 in the adder
   CM5 with the second 64-bit block of the plain text Tp(2).
