= bonding option available
LSB
MSB
C4 = “0” when floating or connected to Vss
0 0 1 C3 C4 C5 C6 1
= “1” when connected to Vcc
C5 = “0” when floating or connected to Vss
= “1” when connected to Vcc
C6 = “0” when connected to Vss
= “1” when floating or connected to Vcc
Note: C4 and C5 have internal pull-low resistors while C6 has an internal pull-high resistor.
