**VL82C322A        SCAMP II, Power Management Unit (PMU)             ?
***Info:
This info was taken from the VL82C315A datasheet.

The   VL82C322A  PMU   dramatically  reduces   overall   system  power
consumption   and  provides   special  features   for  laptop/notebook
AT-compatible computers.   The power reduction is  accomplished via an
activity monitor which  detects inactivity in the system  and slows or
stops the CPU clock and/or removes power from peripheral devices.

The  PMU has  five operational  modes, ON,  DOZE, SLEEP,  SUSPEND, and
OFF. By  monitoring the system  activity, the PMU will  switch between
the  states  to achieve  power  saving  without impacting  the  system
performance.   The  PMU  also  provides  independent  timers  for  LCD
backlight and  display and  an auto  power-on feature  to turn  on the
system  power  via a  push-button  switch,  modem ring  indicator,  or
real-time clock time of day alarm.

The   VL82C322A  can   control   power  to   eight  external   devices
independently  in  all five  operational  modes.  It  can be  used  to
maintain system DRAM during  SUSPEND mode by generating CAS-before-RAS
refresh cycles  or it can  enable self-refresh in DRAM  which supports
this mode. Full system leakage  current control is provided in SUSPEND
mode.   Several  general  purpose  I/O  ports  have  useful  secondary
features. One can  be used to generate programmable tones  or blink an
LED, and several are capable of directly driving LEDs. Two can be used
to add more levels of low battery detection.
