Record Input
: The REC input is an active-LOW record
signal. The device records whenever REC is LOW. This
signal must remain LOW for the duration of the recording.
REC
takes precedence over either playback ( PLAYE or
PLAYL ) signal. If REC is pulled LOW during a playback
cycle, the playback immediately ceases and recording
begins.
A record cycle is completed when REC is pulled HIGH or
the memory space is filled.
And end-of-message marker (EOM) is internally recorded,
enabling a subsequent playback cycle to terminate
appropriately. The device automatically powers down to
standby mode when REC goes HIGH.
Notes:
[1]
The REC signal is debounced for 50 ms on the rising edge to prevent a false retriggering from a push-
button switch.
[2]
During playback, if either
PLAYE or PLAYL is held LOW during EOM or OVF, the device will still
enter into standby mode and the internal oscillator and timing generator will stop. However, the rising
edge of PLAYE and PLAYL are not debounced and any subsequent falling edge (particularly switch
bounce) present on the input pins will initiate another playback.
