C L EAR AID
(A32, A34 TP603)
T h i s signal is u sed by the A32 ADC 1 and the A34 ADC 2. C LADC is
from the ADC control ler to the ADC process switc h . This signal is used
w ith GSW to d eterm i ne the i n put to the AID Converter
asse m b l i es are i n sta l l ed, the C LADC s ignal goes to the A32 ADC 1
assembly's process switch.
