The SAM47 instruction set is specifically designed to support the large register files typically founded in most
KS57-series microcontrollers. The SAM47 instruction set includes 1-bit, 4-bit, and 8-bit instructions for data
manipulation, logical and arithmetic operations, program control, and CPU control. I/O instructions for peripheral
hardware devices are flexible and easy to use. Symbolic hardware names can be substituted as the instruction
operand in place of the actual address. Other important features of the SAM47 instruction set include:
— 1-byte referencing of long instructions (REF instruction)
— Redundant instruction reduction (string effect)
— Skip feature for ADC and SBC instructions
Instruction operands conform to the operand format defined for each instruction. Several instructions have multiple
operand formats.
Predefined values or labels can be used as instruction operands when addressing immediate data. Many of the
symbols for specific registers and flags may also be substituted as labels for operations such DA, mema, memb,
b, and so on. Using instruction labels can greatly simplify programming and debugging tasks.
       
In this section, the following SAM47 instruction set features are described in detail:
— Instruction reference area
— Instruction redundancy reduction
— Flexible bit manipulation
— ADC and SBC instruction skip condition
