FUNCTIONAL DESCRIPTION
PCM1716 has several built-in functions including digital
attenuation, digital de-emphasis, input data format selection,
and others. These functions are software controlled. PCM1716
can be operated in two different modes, software mode or
hardware mode. Software mode is a three-wire interface
using pin 28 (ML), 27 (MC), and 26 (MD).
PCM1716 can also be operated in hardware mode, where
static control signals are used on pin 28 (115, pin 27 (DM1),
pin 26 (DM0) and pin 23 (IWO).
This basic operation mode as software or hardware can be
selected by pin 24 (MODE) as shown in Table II.
MODE (pin 24) = H
Software Mode
MODE (pin 24) = L

TABLE II. Mode Control.
Table III indicates which functions are selectable within the
users 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
PCM1716 in the hardware mode.
