Port 2 LED Indicator
See the description in pins 6, 7, and 8.
Digital IO Ground
1.2V Core Voltage Output. (Internal 1.2V LDO power supply output)
This pin is used to provide 1.2V power supply to all 1.2V power VDDC, VDDA and
VDDAP. It is recommended the pin should be connected to 3.3V power rail by a
100ohm resistor for the internal LDO application.
No connect
EEPROM Enable
EEPROM is enabled and connected when this pin is pull-up.
EEPROM is disabled when this pin is pull-down or no connect.
Port 1 LED Indicator
See the description in pins 3, 4, and 5.
EEPROM Data Out
This pin is connected to DI input of the serial EEPROM.
