FUNCTION
PWRDWN/TXCLK - Input pin valid when XENDEC is not zero (0).
Pwrdwn bits in ECSR
Enable Function bit in ECOR
PWRDN - Legacy power down bit in Control Register.
All internal logic
The Ethernet controller function and
Ethernet PCMCIA Configuration Registers
except for the bit itself. Setting this bit also
lowers the nIREQ/READY line. When
cleared, the nIREQ/READY line is raised.
The Ethernet controller itself except for
the IA, CONF and BASE registers. It does
not reset any PCMCIA Configuration
Register.
RESETS THE FOLLOWING
nIREQ when function is Ready.
Acts as ready line at power up.
I.e. remains low until the chip
(therefore, card) is Ready
OR function of all interrupt bits specified in the Interrupt Status Register
ANDed with their respective Enable bits
