3850 Group (Spec. H)
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
FUNCTIONAL DESCRIPTION
CENTRAL PROCESSING UNIT (CPU)
The 3850 group (spec. H) uses the standard 740 Family instruc-
tion set. Refer to the table of 740 Family addressing modes and
machine instructions or the 740 Family Software Manual for de-
tails on the instruction set.
Machine-resident 740 Family instructions are as follows:
The FST and SLW instructions cannot be used.
The STP, WIT, MUL, and DIV instructions can be used.
[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 ad-
dress are determined by the stack page selection bit. If the stack
page selection bit is
“
0
”
, the high-order 8 bits becomes
“
00
16
”
. If
the stack page selection bit is
“
1
”
, the high-order 8 bits becomes
“
01
16
”
.
The operations of pushing register contents onto the stack and
popping them from the stack are shown in Figure 6.
Store registers other than those described in Figure 6 with pro-
gram when the user needs them during interrupts or subroutine
calls.
[Program Counter (PC)]
The program counter is a 16-bit counter consisting of two 8-bit
registers PC
H
and PC
L
. It is used to indicate the address of the
next instruction to be executed.
