debugging - What does 0D mean in assembly 89 0D 0B00A85E - mov [5EA8000B],ecx -


i'm new assembly , know 0d stands in:

89 0d 0b00a85e - mov [5ea8000b],ecx

the 89 0d 0b00a85e hex representation of machine code mov [5ea8000b], ecx.

the 89 encodes mov r/m16/32, r16/32 instruction. byte follows known "32-bit modr/m byte", , encodes arguments mov. meaning can seen here:

  • the first argument disp32 (the immediate value of -- 0b00a85e -- follows 0d);
  • the second argument ecx (see r32(/r) row @ top).
