Ernie is the codename for the Syscon chip. The Syscon is for exemple responsible for handling button input (including power button), reading/writing to non-volatile storage (NVS) for storing system flags (mostly encrypted and signed). For example IDU flag is stored in NVS. Syscon is also responsible for maintaining the physical address to the resume buffer during [[Suspend]]. Communication between [[Kermit]] and Syscon is mainly through SPI (see [[SceSyscon]]) but there are also some GPIO pins connecting the two. The chip model is NEC/Renesas <code>uPD79F0109</code> and is likely custom designed for Sony.
