Break IC S3F9454B protective system and readout firmware from samsung

Break IC S3F9454B protective system and readout firmware from samsung Microcontroller S3F9454B, the format of firmware will be heximal which can be reprogramme to blank MCU S3F9454B flash memory;

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 after MCU STM32F107RCT6 code recovery.

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” when microcontroller PIC16F684 firmware copying.
