S3P72G9 - Samsung semiconductor

S3P72G9 The S3C72G9 single-chip CMOS microcontroller has been designed for high performance using Samsungs newest 4-bit CPU core/ SAM47 (Samsung Arrangeable M

 
  




   


 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.

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 simpl.
