**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.
