Description
LEDS1-0
Refer to section 5.5 LED Interface, page 8, for a detailed LED pin description. The
initial value of these bits comes from the 93C46.
DVRLOAD
Driver Load.
Software may use this bit to make sure that the driver has been loaded.
1: Driver loaded
0: Driver not loaded
When the command register bits IOEN, MEMEN, and BMEN of the PCI
configuration space are written, the RTL8100C(L) will clear this bit
automatically.
LWAKE active mode: The LWACT bit and LWPTN bit in CONFIG4 register
are used to program the LWAKE pin’s output signal. Depending on the
combination of these two bits, there may be 4 choices of LWAKE signal, i.e.,
active high, active low, positive (high) pulse, and negative (low) pulse. The
output pulse width is about 150ms.
The default value of each of these two bits is 0, i.e., the default output signal of
the LWAKE pin is an active high signal.
