DM9010BI DAVICOM [Davicom Semiconductor, Inc.], DM9010BI Datasheet - Page 47

• Manufacturer Part Number: DM9010BI
• Description: Industrial-temperature 10/100 Mbps Single Chip Ethernet Controller With General Processor Interface
• Manufacturer: DAVICOM [Davicom Semiconductor, Inc.]

10.3 AC Electrical Characteristics & Timing Waveforms
10.3.1 TP Interface
10.3.2 Oscillator/Crystal Timing
10.3.3 Power On Reset Timing
Note: The DM9010BI needs the time about 3ms to down load the setting from EEPROM after PWRST# deasserted,
During the period, the processor command (IOR#, IOW#, AEN#) pins are not recognized even no EEPROM present. So,
please note that processor only access DM9010BI after PWRST# deasserted 3ms.
