SYNC INTERRUPT
In a normal write sequence, the SYNC line is kept low for at
least 24 falling edges of SCLK, and the DAC is updated on the
24th falling edge. However, if SYNC is brought high before the
24th falling edge, this acts as an interrupt to the write sequence.
The shift register is reset and the write sequence is seen as
invalid. Neither an update of the DAC register contents nor a
change in the operating mode occurs (see Figure 30).
POWER-ON RESET
The AD5663 family contains a power-on reset circuit that
controls the output voltage during power-up. The AD5663 DAC
outputs power up to 0 V, the AD5663-1 powers up to midscale,
and the output remains there until a valid write sequence is
made to the DAC. This is useful in applications where it is
important to know the state of the output of the DAC while it is
in the process of powering up. Any events on LDAC or CLR
during power-on reset are ignored.
SOFTWARE RESET
The AD5663 contains a software reset function. Command 101
is reserved for the software reset function (see Table 7). The
software reset command contains two reset modes that are
software-programmable by setting Bit DB0 in the control
register.
Table 9 shows how the state of the bit corresponds to the mode
of operation of the device. Table 10 shows the contents of the
input shift register during the software reset mode of operation.
