Indirect Addressing Register
Location 00H and 02H are indirect addressing registers
that are not physically implemented. Any read/write op-
eration of [00H] and [02H] accesses the RAM pointed to
by MP0 (01H) and MP1 (03H) respectively. Reading lo-
cation 00H or 02H indirectly returns the result 00H.
While, writing it indirectly leads to no operation.
The function of data movement between two indirect ad-
dressing registers is not supported. The memory pointer
registers, MP0 and MP1, are both 8-bit registers used to
access the RAM by combining the corresponding indi-
rect addressing registers.
Accumulator
ACC (05H)
The accumulator (ACC) is related to the ALU opera-
tions. It is also mapped to location 05H of the RAM and
is capable of operating with immediate data. The data
movement between two data memory locations must
pass through the ACC.
Arithmetic and Logic Unit
ALU
This circuit performs 8-bit arithmetic and logic opera-
tions and provides the following functions:
Arithmetic operations (ADD, ADC, SUB, SBC, DAA)
Logic operations (AND, OR, XOR, CPL)
Rotation (RL, RR, RLC, RRC)
Increment and Decrement (INC, DEC)
Branch decision (SZ, SNZ, SIZ, SDZ etc)
Status Register
STATUS
This 8-bit STATUS register (0AH) consists of a zero flag
(Z), carry flag (C), auxiliary carry flag (AC), overflow flag
(OV), power down flag (PDF), watchdog time-out flag
(TO). It also records the status information and controls
the operation sequence.
Except the TO and PDF flags, bits in the status register
can be altered by instructions similar to other registers.

or PDF flags. Operations related to the status register,
