EEPROM Defaults

The signature value of 0xA5 is stored at address 0. A different signature value indicates to the

EEPROM controller that no EEPROM or an un-programmed EEPROM is attached to the device. In

this case, the hardware default values are used, as shown in Table 5.4.

Note: The Configuration Flags are affected by the PWR_SEL and RMT_WKP straps.

GPIO10 Detection Select

This bit selects the detection mode for GPIO10 when operating in PME mode. In PME mode, GPIO10

is usable in both Internal and External PHY mode as a wakeup pin. This parameter defines whether

the wakeup should occur on an active high or active low signal.

0 = Active-low detection for GPIO10.

1 = Active-high detection for GPIO10.

Note:

If GPIO PME Enable is 0, this bit is ignored.
