entire conversion result, 16 SCLK cycles are needed.
Extra clock pulses, occurring after the conversion result
has been clocked out and prior to the rising edge of
CS
, cause the conversion result to be shifted out again.
The MAX1167/MAX1168 internal clock 8-bit-wide data-
transfer mode requires 24 external clock cycles and 25
internal clock cycles for completion.
Force
CS
high after the conversion result is read. For
maximum throughput, force
CS
low again to initiate the
next conversion immediately after the specified mini-
mum time (t
CSW
). Forcing
CS
high in the middle of a
conversion immediately aborts the conversion and
places the MAX1167/MAX1168 in shutdown.
Scan mode allows multiple channels to be scanned
consecutively or one channel to be scanned eight
times. Scan mode can only be enabled when using the
MAX1167/MAX1168 in the internal clock mode. Enable
scanning by setting bits 4 and 3 in the command/con-
figuration/control register (see Tables 3 and 4). In scan
mode, conversion results are stored in memory until the
completion of the last conversion in the sequence.
Upon completion of the last conversion in the
sequence,
EOC
transitions from high to low to indicate
the end of the conversion and shuts down the internal
oscillator. Use the
EOC
high-to-low transition as the sig-
nal to restart the external clock (SCLK). DOUT provides
the conversion results in the same order as the channel
conversion process. The MSB of the first conversion is
available at DOUT on the falling edge of
EOC
(Figure 14).
