All operations to other registers are initiated through
Controls functions such as mode of operation, chan-
Function
the Communications Register. This controls whether
subsequent operations are read or write operations
and also selects the register for that subsequent
operation.
Provides status information on conversions, calibra-
tions and error conditions.
nel configuration, oscillator operation in power-down.
ADC (ADCCON)
This register is used to select the active channel
input, configure the operating input range, and select
unipolar or bipolar operation.
I/O (IOCON)
This register is used to control and configure the
I/O port.
This register determines the amount of averaging
performed by the sinc filter and consequently deter-
mines the data update rate of the AD7708/AD7718.
The filter register determines the update rate for
operation with CHOP enabled and CHOP disabled.
Provides the most up-to-date conversion result for
the selected channel on the AD7718.
Provides the most up-to-date conversion result for
the selected channel on the AD7708.
