Notes:

1. Output ports high impedance on power up, with data, clock, and enable at logic ‘0’

2. If the REF/COMP output is not used, the output should be left open circuit or connected to Vcc, and disabled by

setting RE = 0

3. Bi-directional port. When used as an output, the input logic state is ignored. When used as an input the port should

be switched in to high impedance (off) state.
