NAME
FUNCTION
18
EOC
Active-Low, End-of-Conversion Output. EOC goes low when a conversion is
completed. EOC goes high when a conversion is initiated.
19
CONVST
Convert Start Input. The 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.
20
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.

WR
Active-Low Write Input. Drive WR low to write to the ADC. Configuration
registers are loaded on the rising edge of WR.
62
CS
Active-Low Chip-Select Input. Drive CS low when reading from or writing to
the ADC.
63
RD
Active-Low Read Input. Drive RD low to read from the ADC. Each rising edge
of RD advances the channel output on the data bus.
