 Operation can be switched between quiet mode and continuous mode.
 The CLKRUN signal can be manipulated to restart the PCI clock (LCLK).
• Power-down functions, interrupts, etc.
 The LPC module can be shut down by inputting the LPCPD signal.
 Three pins, PME, LSMI, and LSCI, are provided for general input/output.
