Table 3 ADC levels
Bits 3, 4 and 5 (I2,I1,I0) show the status of the I/O Ports P7,
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.
The 5 level ADC can be used to feed AFC information to
the microprocessor from the IF section of the receiver, as
illustrated in the typical application circuit.
APPLICATION
A typical Application is shown in Fig. 4. All input/output
interface circuits are shown in Fig. 6.
