Notes: 1. “0” connects an external pull-low
resistor to ASn, where n=4, 6.
2. “1” connects no external pull-low
resistor to ASn, where n=4, 6.
System reset
The reset time of the HT8658 and HT8659 is
different. The HT8658 will reset the system if
the RE S key is pressed more than 4 seconds and
reset the playing counter if the RES key is
pressed less than 4 seconds. The HT8659, on
the other hand, will reset the system if the RE S
key is pressed over 2 seconds and reset the
playing counter if the key is pressed less than 2
seconds. Once the playing counter is reset, the
ICs will play back the recorded data from the
beginning by triggering the PLAY key. All of the
recorded data will be deleted after the system is
reset.
Indicate function
The HT8658/HT8659 provide an LE DB pin to
indicate the operation status of the LSI through
an external LE D display. The LE DB pin is of
high impedance and an external L E D is
switched off in the standby state. LE DB, on the
other hand, remains at a low level and LE D is
turned on in the recording state. In the play-
back state, LE D flashes with the volume of
output sounds. When the system is reset, it
flashes at a 2Hz rate.
