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
register.
Subtract SUB Subtracts value specified by operand from content of
@SUB internal register, and inputs result back to same internal
register.
Multiply MUL Multiplies content of internal register by value specified
@MUL by operand, and inputs result back to same internal
register.
Divide DIV Divides content of internal register by value specified
@DIV by operand, and inputs result back to same internal
register.
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.
