Retrieve Microcontroller Chip SAMSUNG S3F9454B memory program from its eeprom and flash, then copy it to other blank Microcontroller which will perform the same functions:
OVERVIEW
The SAM88RCRI instruction set is designed to support the large register file. It includes a full complement of 8-bit arithmetic and logic operations. There are 41 instructions. No special I/O instructions are necessary because I/O control and data registers are mapped directly into the register file. Flexible instructions for bit addressing rotate, and shift operations complete the powerful data manipulation capabilities of the SAM88RCRI instruction set.
REGISTER ADDRESSING
To access an individual register, an 8-bit address in the range 0-255 or the 4-bit address of a working register is specified. Paired registers can be used to construct 13-bit program memory or data memory addresses. For detailed information about register addressing, please refer to Chapter 2, “Address Spaces”.
ADDRESSING MODES
There are six addressing modes: Register (R), Indirect Register (IR), Indexed (X), Direct (DA), Relative (RA), and Immediate (IM). For detailed descriptions of these addressing modes, please refer to Chapter 3, “Addressing Modes”.
