PCM1732
FIGURE 5. Internal Power-On Reset Timing.
FUNCTIONAL DESCRIPTION
The PCM1732 can be operated in two different modes:
software or hardware mode. Software mode is a three-wire
interface using pin 28 (ML), pin 27 (MC), and pin 26 (MD).
PCM1732 can also be operated in hardware mode, where
static control signals are used on pin 28 (ML), pin 27 (DEM),
pin 26 (FSS) and pin 23 (IWO).
The mode of operation (software or hardware) is selected by
pin 24 (MODE), as shown in Table II.
TABLE II. Mode Control.
Table III indicates which functions are selectable within the
chosen mode. All of the functions shown are selectable within
the Software mode, but only de-emphasis control, soft mute
and input data format may be selected when using PCM1732
in the Hardware mode.
