Assert this bit will reset the LAN function of AX88190A. Return a 0 to this bit will leave
the LAN function of AX88190A in a post-reset state as same as that following a hardware
reset. The value of this bit is 0 at power-on.
This bit should be set to 1, the AX88190A always generates Level Mode Interrupt.
These six bits are used to indicate entry of the card configuration table locate in the CIS.
The default value is 0
.
On multifunction PC Card,
Bit 5, Bit 4, Bit 3 : MODEM I/O base registers
Bit 5
Bit 2 : Enable IREQ# Routing
Bit 1 : Enable Base and Limit Registers
Bit 0 : Enable Function
If bit 0 of LCOR is set to 0, this bit is ignored.
If bit 0 of LCOR is set to 1 and this bit is set to 1, the LAN will generate interrupt request
via IREQ# signal. If this bit is set to 0, the LAN will not generate interrupt request via
IREQ# line.
If bit 0 of LCOR is set to 0, this bit is ignored.
If bit 0 of LCOR is set to 1 and this bit is set to 1,only I/O addresses that are qualified by
the Base and Limit registers are passed to LAN function. If this bit is set to 0,all I/O
addresses are passed to LAN function.
If this bit is set to 0, the LAN function is disabled.
If this bit is set to 1, the LAN function is enabled.
