4.3.1.3 Data Transfer Instructions

The data transfer instructions are of three types: the core RAM,

xdata RAM, and the lookup tables. The core RAM transfer

includes transfer between any two core RAM locations or SFRs.

These instructions can use direct, indirect, register, and

immediate addressing. The xdata RAM transfer includes only the

transfer between the accumulator and the xdata RAM location.

It can use only indirect addressing. The lookup tables involve

nothing but the read of program memory using the Indexed

addressing mode. Table 4-3 lists the various data transfer

instructions available.

4.3.1.4 Boolean Instructions

The 8051 core has a separate bit-addressable memory location.

It has 128 bits of bit addressable RAM and a set of SFRs that are

bit addressable. The instruction set includes the whole menu of

bit operations such as move, set, clear, toggle, OR, and AND

instructions and the conditional jump instructions. Table 4-4 lists

the available Boolean instructions.
