Like most memory commands the cmp can access the memory in different sizes: as 32 bit (long word), 16 bit
(word) or 8 bit (byte) data. If invoked just as cmp the default size (32 bit or long words) is used; the same can
be selected explicitely by typing cmp.l instead. If you want to access memory as 16 bit or word data, you
can use the variant cmp.w instead; and to access memory as 8 bit or byte data please use cmp.b.
Please note that the count argument specifies the number of data items to process, i. e. the number of long
words or words or bytes to compare.
=> cmp.l 0x42000000 0x43000000 0x400
Total of 1024 word(s) were the same
=> cmp.w 0x42000000 0x43000000 0x800
Total of 2048 halfword(s) were the same
=> cmp.b 0x42000000 0x43000000 0x1000
Total of 4096 byte(s) were the same
