EC Required Knowledge The first step for a software engineer is to thoroughly understand the relevant specifications, just as understanding the requirements is essential before developing software. Similarly, an EC engineer needs to have a clear understanding of LPC, SMBUS, PS2, and Smart Battery before moving on to the next step. LPC Specification This chapter focuses on the LPC Interface, allowing readers to understand its operating principles and pin functions. Understanding the LPC Interface is essential to finding solutions when problems arise. LPC characteristics X-BUS interface compatible with legacy systems It can be addressed up to 4GB, and the BIOS is not limited to 1MB, nor is the memory device limited to 16MB. It can operate correctly without the need for special driver installation on the operating system. If I/O or MEMORY instructions take a long time, consider using LPC to enter a wait state. LPC-supported devices SUPER I/O – Floppy disk control interface, IR, KBC Audio ...
