The following check should be performed for the continued protection of the customer and service technician.
LEAKAGE CURRENT CHECK
Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.

This pin is also used as the strap pin of the polarity of the INT pin.
When the MDC pin is pull-high, the INT pin low active; otherwise the INT pin is
high active.
Processor interface
DN-V750/V755
1IOR#IProcessor Read command.
This pin is low active at default, its polarity can be modified by EEPROM setting.
See the EEPROM content description for detail.
2IOW#IProcessor Write command.
This pin is low active at default, its polarity can be modified by EEPROM setting.
See the EEPROM content description for detail.
3AENIAddress enable used for ISA mode or
chip select for general processor mode.
In general processor mode, the polarity of this pin can be modified by EEPROM
setting. See the EEPROM content description for detail.
4IOWAITOProcessor command ready
When a command is issued before last command completed, the IOWAIT will be
pulled to low to indicate the current command is waited.

92CMDICommand type:
When high, the access of this command cycle is DATA port.
When low, the access of this command cycle is ADDRESS port.
91IO16Oword command indication
When the access of internal memory is word or dword width, this pin will
be asserted.
This pin is low active at default, its polarity can be modified by EEPROM
setting. See the EEPROM content description for detail.
This pin is high active at default, its polarity can be modified by EEPROM
setting or strap pin MDC. See the EEPROM content description for detail.

I/OProcessor data bus bit 16~31
These pins are used as data bus bits 16~31 when the DM9000 is set to
double word mode (the straps pin EEDO is pull-high and WAKEUP is not
pull-high).
ODouble word command indication
This pins is used as the Double word command indication when the
DM9000 is set to double data word mode and when the access of internal
memory is double word width, this pin will be asserted.
This pin is low active at default, its polarity can be modified by EEPROM
setting. See the EEPROM content description for detail.
64EEDIIData from EEPROM
65EEDOI/OData to EEPROM
This pin is also as a strap pin. Combine with strap pin WOL, it can set the
data width of the internal memory access.
The decoder table is the following, where the logic 1 means the strap pin
is pull-high.
WAKEUP EEDO data width
0 0 word
0 1 double word
1 0 byte
1 1 reserved
66EECKOClock to EEPROM
67EECSI/OChip Select to EEPROM
This pin is also used as a strap pin to define the LED modes.
When it is pull-high, the LED mode is the mode 1;
Otherwise it is mode 0.
