P5 and P4 respectively. A logic 0 indicates a low level and a logic
1 a high level. If the ports are to be used as inputs they should
be programmed to a high impedance state (logic 1). These
inputs will then respond to data complying with TTL type voltage
levels. Bits 6, 7 and 8 (A2,A1,A0) combine to give the output of
the 5 level ADC.
