FDC37M81X

PC98/99 Compliant Enhanced Super I/O Controller with Keyboard/Mouse Wake-Up

SMSC -> Microchip 

Note 5:

Note 6:

Note 7:

Requires external pull-up resistor.

When SYSOPT function is used on nRTS1/SYSOPT pin, an external pulldown register is

required to put the base I/O address for configuration at 0x3F0. An external pullup resistor is

required to move the base I/O address for configuration to 0x370.

VTR can be connected to VCC if no wakeup functionality is required.
