EOC
Active-Low End of Conversion Output. EOC goes low when conversion is
completed. EOC goes high when a conversion is initiated.
18
CONVST
Convert Start Input. Rising edge of CONVST ends sample and starts a
conversion on the captured sample. The ADC is in acquisition mode when
CONVST is low and CONVST mode = 0.
19
SHDN
Shutdown Input. If SHDN is held high, the entire device enters and stays in a
low-current state. Contents of the Configuration register are not lost when in
the shutdown state.
