Option Switches; Analog To Digital Converter (Adc) - S160, S161 - Motorola G24 Developer's Manual

Option Switches

The Developer Board contains 7 option switches that are described in the following paragraphs.

Analog to Digital Converter (ADC) - S160, S161

The Developer Board can route up to 8 different analog voltage levels to the 3 G24 analog to
digital converters, using the S160 and S161 switches.

Voltage level is set using the S161 switches and routing of the voltage to the desired A/D is done
using the S160 switched.
When simulating a desired voltage level to either of the A/D lines, perform the following steps:
1. Turn the desired voltage level switch (labeled LEVEL1-LEVEL8) to ON.
Note:
2. Move the desired A/D input switch (labeled ADC1-ADC3) to ON. Selecting more then one
ADC channel is allowed.
S161 switches are labeled LEVEL1 to LEVEL8 respectively. Voltage levels are shown in
Table 2-12.

S161
In order to have the correct voltage level, verify that only a single level switch is turned
ON.
