At times the discussion will refer to M as a memory location.
It
should be understood that what
is really meant is the effective address -- that is, the memory location specified by M and
the addressing mode. M is used for brevity.
The following word times assume that direct addressing is used. Add one additional word
time when using indirect addressing.
All instructions that address memory are also indirectly
addressable.
