The W83977EF also supports Power-loss control, and ensures that the system never fails 
to detect any Wake-Up event provided by a chipset such as INTEL PIIX4 TM. 
W83977EF is made to fully comply with Microsoft PC98 Hardware Design Guide. IRQs, 
DMAs, and I/O space resource are flexible to adjust to meet ISA PnP requirements. 
Moreover, W83977EF is made to meet the specification of PC98's requirements in power 
management: ACPI and DPM (Device Power Management). 
Another benifit is that W83977EF has the same pin assignment as W83977AF, W83977F, 
W83977TF, W83977ATF. This makes the design very flexible.   
The features are as below: 

•  Plug & Play 1.0A compatible 
•  Supports 12 IRQs, 4 DMA channels, full 16-bit address decoding 
•  Capable of ISA Bus IRQ Sharing 
•  Compliant with Microsoft PC98 Hardware Design Guide 
•  Supports DPM (Device Power Management), ACPI 
•  Reports ACPI status interrupt by SCI# signal issued from any of the 12 IQRs pins or 

GPIO xx

•  Single 24/48 Mhz clock input 

A Compact Flash type II connector is connected to the secondary IDE controller. The 
Compact Flash storage card is IDE compatible. It is an ideal replacement for standard IDE 
hard drives. The solid-state design offers no seek errors even under extreme shock and 
vibration conditions. The Compact Flash storage card is extremely small and highly suitable 
for rugged environments, thus providing an excellent solution for mobile applications with 
space limitations. It is fully compatible with all consumer applications designed for data 
storage PC card, PDA, and Smart Cellular Phones, allowing simple use for the end user. 
The Compact Flash storage card is O/S independent, thus offering an optimal solution for 
embedded systems operating in non-standard computing environments. The Compact 
Flash storage card is IDE compatible and offers various capacities.
