Connection Requirements

C17 / E16 / G2

These balls must be connected to GND through an external pull

resistor if unused

G1 / F3 / E2 / K2 / K3 / H2

These balls must be connect to the corresponding power supply

through an external pull resistor if unused

N17 / N16 / N15 / P17 / P16 / M15 / L17 / M14 / L16

These balls must be connected together to GND through a single

external 10k-ohm resistor if unused.
