说明

• Microcontroller-Based Serial Port SPI Interface Boot Circuit, that describes the operation of a general-purpose, microcontroller-based Serial Port Interface (SPI) boot circuit. This is a low cost solution for users who need to modify some of their device's parameters at power up. This circuit addresses a 3-wire SPI application for programming converters or any device that has a SPI option, and sends commands to user-defined SPI registers
