RESET, STANDBY, AND SHUTDOWN MODES
1. PC Card Mode
* :The STBY bit of the DLCR7 is set automatically.
2. ISA Bus Mode
Operation
Input of 1 to external reset register
Write to reset registers: RES0 to RES7
(any values)
The LAN controller and 10BASE-T transceiver are initialized.
The LAN controller and 10BASE-T transceiver are initialized but
BMPR16 and BMPR17 are not.
The LAN controller is initialized.
The previous values of the control registers (DLCR, MAR, and
BMPR) in the LAN controller are retained.
The TP transceiver is in the power-down mode.
Standby mode
The clock stops and current consumption is reduced to about 10%.
Shutdown mode
Crystal oscillation stops and current consumption is reduced to
about 1%.

Interface
Input of 1 to
external
reset register
LAN Controller
Operation
The CCR is initialized.
The I/O card interface is switched to the IC memory
interface.
The LAN controller and 10BASE-T transceiver are also
initialized.
Same as above, except this bit not cleared
