DESCRIPTION
Software Reset
Assert this bit will reset the MODEM function of AX88190. Return a 0 to this bit will
leave the MODEM function of AX88190 in a post-reset state as same as that following a
hardware reset. The value of this bit is 0 at power-on.
Level IRQ
This bit should be set to 1, the AX88190 always generates Level Mode Interrupt.
Function Configuration Index
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, Bit4 : Reserved
Bit 3 : IREQ# route to STSCHG#
If bit 0 of MCOR is set to 0, this bit is ignored.
If both bit 0 and bit 2 of MCOR are set to 1 and this bit is set to 1, the MODEM will route
interrupt request to STSCHG# signal. If this bit is set to 0, the MODEM will generate
interrupt request via IREQ# line.
Bit 2 : Enable IREQ# Routing
If bit 0 of MCOR is set to 0, this bit is ignored.
If bit 0 of MCOR is set to 1 and this bit is set to 1, the MODEM will generate interrupt
request via IREQ# signal. If this bit is set to 0, the MODEM will not generate interrupt
request via IREQ# line.
Bit 1 : Enable Base and Limit Registers
If bit 0 of MCOR is set to 0, this bit is ignored.
If bit 0 of MCOR 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 MODEM function. If this bit is set to 0,all
I/O addresses are passed to LAN function.
Bit 0 : Enable Function
If this bit is set to 0, the MODEM function is disabled.
If this bit is set to 1, the MODEM function is enabled.
