If the device is idle and the playback pointer is
not
currently pointing to the first or last
message:

No message is erased.
SE3, if present, will be played and the LED will flash twice.
Play pointer will be unchanged.
If the device is currently playing the first or last message, pressing
ERASE
will delete
the current message, as in the related cases described above.
b)
Global Erase
: Level-triggering this pin at Low for more than 2.5 seconds initiates the
Global Erase operation and deletes all messages, except the SEs. If SEs are present, the
device will play SE1 three times after
ERASE
is held for 2.5 seconds. If
ERASE
is not
released during the playback of SE1, all messages will be erased, and the chip will play
SE4. See Figure 7.1 for the operation details. The
ERASE
is debounced internally.
Triggering
ERASE
for individual erase during a record or forward operation is an illegal
operation and will be ignored. However, triggering
ERASE
for an individual erase operation
during playback will delete the current played message, if it is the first or last one.
