B-3 Arithmetic instructions

Instruction name Mnemonic Outline of process

Data Memory Write DW Writes constant directly into data memory.

Trimmer Setting TMIN Converts rotation angle of trimmer into a number from

@TMIN 0 to 249, and inputs it back to internal register.

Load A LDA Inputs value specified by operand to internal register.

@LDA * Inputs current value to internal register when timer/

counter is specified by operand.

Store A STA Transfers content of internal register to destination

@STA specified by operand.

* Preset value is changed when timer/counter is

specified by operand.

Compare CMP Compares content of internal register with value

@CMP specified by operand, and outputs result to 2009 to

2011.

Add ADD Adds value specified by operand to content of internal

@ADD register, and inputs result back to same internal

Subtract SUB Subtracts value specified by operand from content of

@SUB internal register, and inputs result back to same internal

Multiply MUL Multiplies content of internal register by value specified

@MUL by operand, and inputs result back to same internal

Divide DIV Divides content of internal register by value specified

@DIV by operand, and inputs result back to same internal

And A ANDA ANDs content of internal register and value specified

@ANDA by operand for each of 16 bits, and inputs result back

to same internal register.

Or A ORA ORs content of internal register and value specified by

@ORA operand for each of 16 bits, and inputs result back to

same internal register.

Exclusive Or A EORA EXCLUSIVE ORs content of internal register and value

@EORA specified by operand for each of 16 bits, and inputs

result back to same internal register.

Shift Right A SRA Moves content of internal register serially right by value

@SRA specified by operand.

Shift Left A SLA Moves content of internal register serially left by value

@SLA specified by operand.

Rotate Right A RRA Rotates content of internal register clockwise by value

@RRA specified by operand.

Rotate Left A RLA Rotates content of internal register counterclockwise by

@RLA value specified by operand.

Complement COM Inverts content of each bit in internal register.

@COM

Increment Memory INC Adds 1 to content of data memory specified by

@INC operand.

Decrement DEC Subtracts 1 from content of data memory specified by

Memory @DEC operand.

Multiplexer MPX Converts one digit data of internal register specified by

@MPX operand into 16-bit data.

Demultiplexer DMX Converts into a value in position of most significant bit

@DMX in internal register.
