The A/D converter is shared between the two current
generators but the look-up tables, D/A converters, control
bits, and selection bits can be set completely independently.
Bits D1DAS and D2DAS are used to bypass the A/D
converter and look-up tables, allowing direct access to the
inputs of the D/A converters with the bytes in control
registers 3 and 4 respectively. See Figure 9 and the
descriptions of the control bits starting on page 9.
Bits I1DS and I2DS in Control Register 0 select the direction
of the currents through pins I1 and I2 independently See
Figure 8 and the descriptions of the control bits starting on
page 9.
Power-on Reset
When power is applied to the V
CC
pin of the X96012, the
device undergoes a strict sequence of events before the
current outputs of the D/A converters are enabled.
When the voltage at V
CC
becomes larger than the power-on
reset threshold voltage (V
POR
), the device recalls all control
bits from non-volatile memory into volatile registers. Next,
the analog circuits are powered up. When the voltage at Vcc
becomes larger than a second voltage threshold (V
ADCOK
),
the ADC is enabled. In the default case, after the ADC
performs four consecutive conversions with the same exact
result, the ADC output is used to select a byte from each
look-up table. Those bytes become the input of the DACs.
