Revision A2
3. Selective Erase
When the system is operated in multi-segment mode, voice segments can be erased selectively
instead of sequentially. Users can play the voice segments one by one until they reach the segment
to be erased, and then stop playing and press the ERASE key. The current voice segment will be
erased and the CAP value will be changed to the previous voice segment. The LED will light during
the erasing procedure to indicate that the system is busy, and all input triggers will be disabled except
for RESET.
4. Chip Erase
Pressing and holding the RESET key for more than two seconds will clear all data in the flash
EPROM.
5. Function Keys
In normal mode, eight input trigger pins with built-in debounce circuitry are used to operate the
W51300. These eight pins are described below.
L_REC
L_REC is an active-high, level-triggered recording pin with an internal 500 K
pull-low resistor. When
this pin goes high, the device starts recording and continues until this pin is released or the end of the
memory space is reached. When the memory or segment is full, this pin is invalid.
E_PLAY
E_PLAY is an active-high, edge-triggered playback pin with an internal 500 K
pull-low resistor. In
single segment operation, the toggle stop function is enabled. This means a debounced rising edge
on E_PLAY during voice playing will stop the ongoing playback operation immediately. In multi-
segment operation, the toggle skip function is enabled. This means a debounced rising edge on
E_PLAY during voice playing will cause the device to skip to the next voice segment. A rising edge
on this pin while the last voice segment is being played will cause the device to skip to the first voice
segment. This function is useful for fast scanning through a series of messages.
L_ PLAY
L_PLAY is an active-high, level-triggered playback pin with an internal 500 K
pull-low resistor. The
current voice segment will be played back when this pin is pressed. A concatenated loop playing
function is enabled to link all messages in a row and loop back to the first message when the last
message is reached.
STOP
This is an active-high, edge-triggered stop pin with an internal 500 K
pull-low resistor. Pressing this
pin immediately stops playback of the ongoing message. This pin is enabled only while a voice is
playing.
ERASE
ERASE is an active-high, edge-triggered erase pin with an internal 500 K
pull-low resistor. Pressing
this pin erases the current voice segment without affecting the content of the other segments.
FWD
This is an active-high, edge-triggered forward pin with an internal 500 K
pull-low resistor. Pressing
this pin for less than 1 second moves the CAP from the current voice segment to the next one.
Pressing this pin for more than 1 second moves the CAP from the current voice segment to the last
one.
