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 bit manipulation.
(2) Register A and carry flag
Register A is a 4-bit register used for arithmetic, transfer,
exchange, 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 (Figure 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).
