Working Principle

As mentioned earlier, the S9S family of microcontrollers have been designed for use in embedded systems. The microcontrollers consist of a 16-bit RISC-based CPU core and various peripherals. The CPU core consists of 32 16-bit registers and a two-stage pipelined architecture. The instruction set consists of both 16- and 32-bit instructions, allowing for low-level control of the system. The peripherals include periphery interrupts, serial communication, pulse-width modulation, andDMA channels. According to the clock frequency and instruction, the microcontroller can execute specific instructions and respond to interrupt requests. For example, when an interrupt is triggered, the CPU core, which is in idle mode, can change its mode to interrupt mode and handle the interrupt before returning to idle mode.
