P83C557E4/P80C557E4/P89C557E4
Single-chip 8-bit microcontroller

7.
The P8xC557E4 uses the powerful instruction set of the PCB80C51.
It consists of 49 single-byte, 45 two-byte and 17 three-byte
instructions. Using a 16 MHz quartz, 64 of the instructions are
executed in 0.75
μ
s, 45 in 1,5
μ
s and the multiply, divide instructions
in 3
μ
s.
INSTRUCTION SET
A summary of the instruction set is given in Table 43.
The P8xC557E4 has additional Special Function Registers to
control the on-chip peripherals.
7.1
Most instructions have a “destination, source” field that specifies the
data type, addressing modes and operands involved. For all these
instructions, except for MOVs, the destination operand is also the
source operand (e.g., ADD A,R7).
Addressing Modes
There are five kinds of addressing modes:
Register Addressing
–
R0 – R7 (4 banks)
–
A,B,C (bit), AB (2 bytes), DPTR (double byte)
Direct Addressing
–
lower 128 bytes of internal Main RAM (including the 4 R0–R7
register banks)
–
Special Function Registers
–
128 bits in a subset of the internal Main RAM
–
128 bits in a subset of the Special Function Registers
Register-Indirect Addressing
–
internal Main RAM (@R0, @R1, @SP [PUSH/POP])
–
internal Auxiliary RAM (@R0, @R1, @DPTR)
–
external Data Memory (@R0, @R1, @DPTR)
Immediate Addressing
–
Program Memory (in-code 8 bit or 16 bit constant)
Base-Register-plus Index-Register-Indirect Addressing
–
Program Memory look-up table (@DPTR+A, @PC+A)
The first three addressing modes are usable for destination
operands.

209-215 (i.e., the PSW or bits in the PSW) will also affect flag

Notes on instruction set and addressing modes:
Rn
Register R7-R0 of the currently selected Register
Bank.
8-bit internal data location’s address. This could be
an Internal Data RAM location (0-127) or a SFR
[i.e., I/O port, control register, status register, etc.
(128-255)].
8-bit RAM location addressed indirectly through
register R1 or R0 of the actual register bank.
8-bit constant included in the instruction.
16-bit constant included in the instruction
16-bit destination address. Used by LCALL and
LJMP. A branch can be anywhere within the
64 Kbytes Program Memory address space.
11-bit destination address. Used by ACALL and
AJMP. The branch will be within the same 2 Kbytes
page of program memory as the first byte of the
following instruction.
Signed (two’s complement) 8-bit offset byte. Used
by SJMP and all conditional jumps. Range is –128
to +127 bytes relative to first byte of the following
instruction.
Direct Addressed bit in Internal Data RAM or
Special Function Register.
