***Features:
o   Provides eight trigger input channels for monitoring activities 
    such as keyboard, video, hard disk, floppy disk, and user defined 
    device.
o   Provides eight power control outputs
o   Each power control output status can be determined by the 
    combinations of the eight trigger inputs
o   Provides eight user programmable time-out timers.
o   Flexible timer scales:
      2 timers from 1/8 second to 14 seconds
      4 timers from 1 minute to 15 minutes
      1 timer from 2 minutes to 210 minutes
      1 timer from 4 minutes to 7 hours
o   Each trigger input can select one of the two timer scales
o   No glitch CPU clock switching functions
o   Supports CPU clock up to 66 MHz
o   Generates 16 MHz clock for AT Bus
o   Generates 32.768 KHz for both RTC and Ao02020 by using 32.768 KHz 
    crystal
o   Supports Modem ring power-on
o   Supports scheduled power-on
o   Supports cover switch power-down/on
o   Supports Suspend and Resume
o   Provides six operation modes:
      Full Operation mode
      Rest mode
      Standby mode
      Shutdown mode
      Freeze mode
      Off mode
o   Predefined mode transition among Normal Rest. and Standby modes
o   Programmable transitions of operation modes
o   Provides interrupt request for suspend resume operation
o   Interrupt request output can be masked
o   Supports Programmable Slow Refresh in Shutdown and Freeze modes
o   Supports CAS before RAS refresh
o   80-pin QFP
