Examples :
2.3.8
The result of an instruction using this addressing mode is
placed within the RAM memory. Operand 1 is the
address of the result. Operand 2 is an address that
points to a location in the RAM memory that is the source
for the instruction. This addressing mode is only valid on
the MOV instruction. The instruction using this address-
ing mode is three bytes in length.

Example :
2.3.9
The result of an instruction using this addressing mode is
placed in the Accumulator. Operand 1 is an address
pointing to a location within the memory space, which
contains an address (the indirect address) for the source
of the instruction. The indirect address is incremented as
part of the instruction execution. This addressing mode
is only valid on the MVI instruction. The instruction using
this addressing mode is two bytes in length. See Sec-
tion 7. Instruction Set in PSoC Designer: Assembly

2.3.10 Destination Indirect Post Increment
The result of an instruction using this addressing mode is
placed within the memory space. Operand 1 is an
address pointing to a location within the memory space,
which contains an address (the indirect address) for the
destination of the instruction. The indirect address is
incremented as part of the instruction execution. The
source for the instruction is the Accumulator. This
addressing mode is only valid on the MVI instruction.
The instruction using this addressing mode is two bytes
in length.
