W83759A Datasheet, PDF (32/41 Pages) Winbond – ADVANCED VL-IDE DISK CONTROLLER

W83759A
After power on, the W83759A automatically enters the "Auto-Power-Down" (APD) mode. In this mode
the only active logic inside the W83759A is the host address decoder and bus tracking state machine.
Power is saved by not switching logic inside the W83759A that is not being utilized. Whenever an IDE
transfer cycle is detected, the W83759A leaves APD mode and the entire chip becomes active. The
W83759A enters APD mode again after the completion of an IDE transfer cycle.
To support deep-green systems, the W83759A also provides advanced power saving modes, standby
mode, and suspend mode. When standby mode is enabled ( STBY bit goes low), all of the logic
inside the W83759A is stopped until standby mode is disabled ( STBY bit goes high). When suspend
mode is enabled (SUSPEN bit goes high and DMASL is low on SYSRST rising), the W83759A will
enter suspend state when SUSP goes low and return to normal state when SUSP goes high.
