The options are summarized in the following tables:
D/A Converter 1 Access Summary
D/A Converter 2 Access Summary
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 4 and 5 respectively. See Figure 6,
and the descriptions of the control bits.
Bits I1DS and I2DS in Control Register 0 select the
direction of the currents through pins I1 and I2
independently See Figure 5, and the descriptions of
the control bits.
POWER ON RESET
When power is applied to the Vcc pin of the X9530, the
device undergoes a strict sequence of events before
the current outputs of the D/A converters are enabled.
When the voltage at Vcc 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. During all the previous sequence the input
of both DACs are 00h. If bit ADCfiltOff is “1”, only one
ADC conversion is necessary. Bits D1DAS, D2DAS,
L1DAS, and L2DAS, also modify the way the two DACs
are accessed the first time after power up, as
described in “Control Register 5” on page 6.
The X9530 is a hot pluggable device. Voltage
distrubances on the Vcc pin are handled by the power-
on reset circuit, allowing proper operation during hot
plug-in applications.
SERIAL INTERFACE
Serial Interface Conventions
The device supports a bidirectional bus oriented
protocol. The protocol defines any device that sends
data onto the bus as a transmitter, and the receiving
device as the receiver. The device controlling the
transfer is called the master and the device being
controlled is called the slave. The master always
initiates data transfers, and provides the clock for both
transmit and receive operations. The X9530 operates
as a slave in all applications.
