s 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
The LAN controller and 10BASE-T transceiver are initialized.
Write to reset registers: RES0 to RES7
(any values)
The LAN controller and 10BASE-T transceiver are initialized but
BMPR16 and BMPR17 are not.
DLCR6 Bit 7
ENA DLC = 1
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.
DLCR7 Bit 5
STBY = 0
BMPR14 Bit 4
SHUT DWN MODE = 0
Standby mode
The clock stops and current consumption is reduced to about 10%.
BMPR14 Bit 4
SHUT DWN MODE = 1
Shutdown mode
Crystal oscillation stops and current consumption is reduced to
about 1%.
Interface
LAN Controller
Operation
Input of 1 to
external
reset register
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.
CCR0 Bit 7
SRESET = 1
Same as above, except this bit not cleared
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.
DLCR6 Bit 7
ENA DLC = 1
The LAN controller is initialized.
The previous values of the control registers (DLCR,
MAR, and BMPR) in the LAN controller are retained.
The TP or AUI transceiver is in the power-down mode.
CCR1 Bit 2
PwrDwn = 1
DLCR7 Bit 5
STBY = 0*
BMPR14 Bit 4
SHUT DWN MODE = 0
Standby mode
The clock stops and current consumption is reduced to
about 10%.
BMPR14 Bit 4
SHUT DWN MODE = 1
Shutdown mode
Crystal oscillation stops and current consumption is
reduced to about 1%.
