Signal name Pin # Type(I/O) Signal description
SCL 92 I/O EEPROM bus clock. If no EEPROM is present, connect this pin
to ground.
Refer to EEPROM application notes for board pull-up requirements.
SDA 89 I/O EEPROM bus data. If no EEPROM is present, connect this pin
to ground.
Refer to EEPROM app notes for board pull-up requirements.

Signal name Pin # Type(I/O) Signal description
GPIO[0] 9 I/O (int. PU) GENERAL PURPOSE I/O: The GPIO register allows the
GPIO[1] 12 user to define each grouping (GPIO [0, 1], GPIO [2, 3], GPIO [4, 5],
GPIO[2] 13 GPIO[6, 7], GPIO [8, 9], GPIO [10, 11], GPIO [12, 13],
GPIO[3] 14 GPIO [14, 15] ) as either input or output bits. These bits can
GPIO[4] 15 be used for functions such as LED control or user-defined
GPIO[5] 16 input control.
