Megawin MPC82G516A 8-bit Microcontroller User Manual introduces the features of the product, including overview, functions, block diagram, pins, memory organization, special function registers, on-chip extended RAM, external data memory access, double data pointer register, I/O structure, timer/counter, etc.
This manual describes the hardware architecture of the MPC82G516A 8‑bit microcontroller, including pin assignments, special function registers (SFRs), internal RAM, XRAM, timers, UART, PCA, SPI, ADC, and watchdog timer. It also covers power‑up modes, clock configuration, and in‑system programming interfaces such as ISP, IAP, and ICP.
The document contains tables of register maps, timing diagrams, and example code snippets to help developers configure peripherals, set baud rates, and implement interrupt handling. Package options, voltage requirements, and oscillator frequency tables are also provided. This manual is written in Japanese.
