The MAX5174/MAX5176 accepts one 16-bit packet or
two 8-bit packets sent while
CS
remains low. The
MAX5174/MAX5176 allow the following to be config-
ured:
Clock edge on which serial data output (DOUT) is
clocked.
State of the user-programmable logic output.
Configuration of the reset state.
Specific commands for setting these are shown in
Table 1.
The general timing diagram in Figure 4 illustrates how
the MAX5174/MAX5176 acquires data.
CS
must go low
at least t
CSS
before the rising edge of the serial clock
(SCLK). With
CS
low, data is clocked into the register
on the rising edge of SCLK. The maximum serial clock
frequency guaranteed for proper operation is 10MHz
for the MAX5174 and 6MHz for the MAX5176. See
Figure 5 for a detailed timing diagram of the serial inter-
face.
S erial Data Output (DOUT )
The serial-data output (DOUT) is the internal shift regis-
ter’s output and allows for daisy-chaining of multiple
devices as well as data readback (see Applications
Information. By default upon start-up, data shifts out of
DOUT on the serial clock’s rising edge (Mode 0) and
provides a lag of 16 clock cycles, thus maintaining SPI,
QSPI, and MICROWIRE compatibility. However, if the
device is programmed for Mode 1, then the output data
lags DIN by 16.5 clock cycles and is clocked out on the
serial clock’s rising edge. During shutdown, DOUT
retains its last digital state prior to shutdown.
