M
The digital output, DOUT, lags the digital input signal,
DIN by 8.5 clock cycles. Force
CS
high to disable
DOUT, placing DOUT in three-state mode. Force
CS
low to enable DOUT and disable three-state mode.
Force
CS
high, after a word has been written to the
MAX5408
–
MAX5411 to make a readback request. The
next
CS
low period writes the requested data to DOUT.
A readback request overwrites any previous data in the
shift register. Note that the data appears at DOUT in
the order: A0, A1, A2, D4, D3, D2, D1, D0. A0 will be
available after the first high-to-low transition of SCLK
when
CS
is low. The input continues to load the shift
register while data is being read out of the MAX5408
–
MAX5411. The input data appears at DOUT 8.5 clock
cycles later. A
CS
transition from low-to-high latches
the input data. For any control byte, the state of SCLK
must be the same for both
CS
low-to-high transitions
and
CS
high-to-low transitions in order to preserve the
data at DOUT while
CS
transitions.
Zero-Crossing Detection
The zero-crossing detection register enables the zero-
crossing detect feature. The zero-crossing detect fea-
ture reduces the audible noise (
“
clicks and pops
”
) that
result from wiper transitions. The wiper changes posi-
tion only when the voltage at L_ is the same as the volt-
age at H_. Each wiper has a zero-crossing and timeout
circuit (see Figure 2). With zero-crossing enabled, the
MAX5408
–
MAX5411 change wiper position after 50ms
or when zero crossing is detected.
