EEPROM Microwire Chip Select: In Microwire
EEPROM mode (EEPROM_TYPE = 0), this pin is
the Microwire EEPROM chip select output.
Note:
EEPROM Size Strap 0: Configures the low bit of
the EEPROM size range as specified in
10.2, "I2C/Microwire Master EEPROM Controller,"
on page
LED Enable Strap: Configures the default value
for the LED_EN bits in the
Register
LED/GPIO pins are configured as GPIOs. When
latched high, all 8 LED/GPIO pins are configured
as LEDs. See
PHY Address Select Strap: Configures the default
MII management address values for the PHYs
(Virtual, Port 1, and Port 2) as detailed in
7.1.1, "PHY Addressing," on page
