FUNCTION BLOCK OPERATIONS
CPU
(1) Arithmetic logic unit (ALU)
The arithmetic logic unit ALU performs 4-bit arithmetic such as 4-
bit data addition, comparison, AND operation, OR operation, and
bit manipulation.
(2) Register A and carry flag
Register A is a 4-bit register used for arithmetic, transfer, ex-
change, and I/O operation.
Carry flag CY is a 1-bit flag that is set to “1” when there is a carry
with the AMC instruction (Figure 1).
It is unchanged with both A n instruction and AM instruction. The
value of A0 is stored in carry flag CY with the RAR instruction (Fig-
ure 2).
Carry flag CY can be set to “1” with the SC instruction and cleared
to “0” with the RC instruction.
(3) Registers B and E
Register B is a 4-bit register used for temporary storage of 4-bit
data, and for 8-bit data transfer together with register A.
Register E is an 8-bit register. It can be used for 8-bit data transfer
with register B used as the high-order 4 bits and register A as the
low-order 4 bits (Figure 3).
(4) Register D
Register D is a 3-bit register.
It is used to store a 7-bit ROM address together with register A and
is used as a pointer within the specified page when the TABP p,
BLA p, or BMLA p instruction is executed (Figure 4).
