PORT ADC1 Input
PORT ADC2 Input
Positive supply voltage (8...11V)
Data bus input: Bus-mode select
Must be Low for I
Data bus input: Clock
Clock input of the serial control interface with Schmitt-Trigger input stage
Data bus input / output: Bidirectional Data-input/output
Data input of the serial control interface with Schmitt-Trigger input stage in write-mode. Data output in read-
mode.
Bus input: Enable
Enable input of the serial control interface with Schmitt-Trigger input stage. When EN=H the input signals
CLK and DA are disabled. When EN=L the serial control interface is enabled. The received data are
transferred to the registers with the positive edge of the EN_Q-signal.
