MITSUBISHI MICROCOMPUTERS
SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
PRELIMINARY
Notice: This is not a final specification.
Some parametric limits are subject to change.
CENTRAL PROCESSING UNIT (CPU)
The CPU has 13 registers, and they are shown in Figure 6. Each of
these registers is described below.
ACCUMULATOR A (A)
Accumulator A is the main register of the microcomputer. It consists
of 16 bits and the low-order 8 bits can be used separately. Data
length flag m determines whether the register is used as 16-bit reg-
ister or as 8-bit register. It is used as a 16-bit register when flag m is
“0” and as an 8-bit register when flag m is “1”. Flag m is a part of the
processor status register (PS) which is described later.
Data operations such as calculations, data transfer, input/output,
etc., are executed mainly through accumulator A.
ACCUMULATOR B (B)
Accumulator B has the same functions as accumulator A, but the use
of accumulator B requires more instruction bytes and execution
cycles than accumulator A.
ACCUMULATOR E
Accumulator E is a 32-bit register and consists of accumulator A
(low-order 16 bits) and accumulator B (high-order 16 bits). It is used
for 32-bit data processing.
INDEX REGISTER X (X)
Index register X consists of 16 bits and the low-order 8 bits can be
used separately. Index register length flag x determines whether the
register is used as 16-bit register or as 8-bit register. It is used as a
16-bit register when flag x is “0” and as an 8-bit register when flag x
is “1”. Flag x is a part of the processor status register (PS) which is
described later.
In index addressing modes in which register X is used as the index
register, the contents of this address are added to obtain the real ad-
dress.
Index register X functions as a pointer register which indicates an
address of data table in instructions MVP, MVN, RMPA (Repeat
MultiPly and Accumulate).
INDEX REGISTER Y (Y)
Index register Y consists of 16 bits and the low-order 8 bits can be
used separately. The index register length flag x determines whether
the register is used as 16-bit register or as 8-bit register. It is used as
a 16-bit register when flag x is “0” and as an 8-bit register when flag
x is “1”. Flag x is a part of the processor status register (PS) which is
described later.
In index addressing modes in which register Y is used as the index
register, the contents of this address are added to obtain the real ad-
dress.
Index register Y functions as a pointer register which indicates an
address of data table in instructions MVP, MVN, RMPA (Repeat
MultiPly and Accumulate).
