Default Configuration Option
The SMSC device can be configured via its internal default configuration. Please see Section 7.2.2,
"EEPROM Data Descriptor" for specific details on how to enable default configuration. Please refer to
Table 7.1 for the internal default values that are loaded when this option is selected.
7.3.1
External Hardware RESET_N
A valid hardware reset is defined as assertion of RESET_N for a minimum of 1
μs after all power
supplies are within operating range. While reset is asserted, the device (and its associated external
circuitry) consumes less than 500
μA of current from the upstream USB power source.
Assertion of RESET_N (external pin) causes the following:
1. The PHY is disabled and the differential pair will be in a high-impedance state.
2. All transactions immediately terminate; no states are saved.
3. All internal registers return to the default state.
4. The external crystal oscillator is halted.
5. The PLL is halted.
6. The processor is reset.
7. All media interfaces are reset.
