RESET
must stay active for at least 1
μ
sec after all supply rails reach their proper
specifications.

VOL Operation
Pulsing
VOL
Low changes the volume output. Each pulse on
VOL
will decrease the volume
until the minimum setting is reached. Subsequent pulses will increase the volume until the
maximum level is reached and the cycle will start again. There are 8 steps of volume control.
Each step changes the volume by 4 dB. The
RESET
operation will re-initialize the volume level to the default state, which is the maximum
level.
VOL
is debounced internally. A
7.1.7
FT (Feed-Through) Operation
The
FT
controls the feed-through path from the input to the output of the chip. When
FT
is
held Low, FT mode is enabled. By factory default, FT mode will pass AnaIn to SPK and AUD
outputs if the device is idle. It will record AnaIn to the memory during a record operation.

EATURE
(O
PTIONAL
)
If this optional feature is enabled, after a recording operation, the LED output will blink once every
few seconds to indicate the presence of a new message. After a subsequent playback operation,
the vAlert will stop flashing.

DITING
SE editing can be accessed via push buttons. The first sixteen addresses are shared equally by
four Sound Effects (SE1, SE2, SE3, and SE4).
7.3.1
Sound Effects
The functions of SEs are as follows:
o
o
o
o
SE1: Beginning of recording, forward or global erase warning
SE2: End of recording, single erase or forward from last message
SE3: Invalid operation
SE4: Global erase
Whether or not the SEs are programmed, the LED will flash accordingly. The LED flashes
once for SE1, twice for SE2, and so on. The frequency of flashing depends upon the
sampling frequency selected and the power supply level used.
