Product data sheet
The selection of a non-existing input channel results in the highest available channel
number being allocated. Therefore, if the auto-increment flag is set, the next selected
channel is always channel 0.
After power-on all bits of the control register are reset to logic 0. The DAC and the
oscillator are disabled for power saving. The analog output is switched to a
high-impedance state.
The most significant bits of both nibbles are reserved for oscillator control. Bit 7 and bit 3
can be set when the interface frequency is f
two bits to logic 1 sets the internal frequency to half and the accuracy of the A/D and D/A
conversion is 1 LSB as indicated in
The oscillator output is disabled in normal operation (pin OSC is LOW). Setting bit 7 to
logic 0 and bit 3 to logic 1 will enable this output in order to observe the oscillator
frequency (divided by 4).
