FUNCTIONAL DESCRIPTION
CENTRAL PROCESSING UNIT (CPU)
The 38K2 group uses the standard 740 family instruction set. Re-
fer to the table of 740 family addressing modes and machine
instructions or the 740 Family Software Manual for details on the
instruction set.
Machine-resident 740 family instructions are as follows:
The FST and SLW instruction cannot be used.
The STP, WIT, MUL, and DIV instruction can be used.
The CPU has the 6 registers. The register structure is shown in
Figure 5.
[Accumulator (A)]
The accumulator is an 8-bit register. Data operations such as data
transfer, etc., are executed mainly through the accumulator.
[Index Register X (X)]
The index register X is an 8-bit register. In the index addressing
modes, the value of the OPERAND is added to the contents of
register X and specifies the real address.
[Index Register Y (Y)]
The index register Y is an 8-bit register. In partial instruction, the
value of the OPERAND is added to the contents of register Y and
specifies the real address.
[Stack Pointer (S)]
The stack pointer is an 8-bit register used during subroutine calls
and interrupts. This register indicates start address of stored area
(stack) for storing registers during subroutine calls and interrupts.
The low-order 8 bits of the stack address are determined by the
contents of the stack pointer. The high-order 8 bits of the stack
address are determined by the stack page selection bit. If the
stack page selection bit is “0” , the high-order 8 bits becomes
“0016”. If the stack page selection bit is “1”, the high-order 8 bits
becomes “0116”.
Figure 6 shows the store and the return movement into the stack.
If there are registers other than those described in Figure 5, the
users need to store them with the program.
[Program Counter (PC)]
The program counter is a 16-bit counter consisting of two 8-bit
registers PCH and PCL. It is used to indicate the address of the
next instruction to be executed.
