Recording starts whenever a sound input is  
detected. It then stops once a 0.5 seconds si-  
lence is detected or the recording capacity is  
full. After that, talking back comes into play.  
Motor  
The HT8656 provides a motor driving pin. The  
motor is turned on during playing but off once  
talking back is terminated.  
Play function  
The HT8656 stops to play back the recorded  
sounds when an interval of silence lasts 0.5  
seconds during recording. Its sampling rate is  
the same as the rate of recording sounds.  
LED  
The LED pin displays the status of the HT8656.  
LED is switched ON when the IC is in the  
standby state. Its intensity varies inversely  
with the sound volume when the IC is in the  
recording state. In the playing state, the LED is  
switched OFF.  
Power control  
The HT8656 provides a START pin for power  
control. The START pin is of high impedance  
and switch Q is turned off initially. After the  
START pin is triggered, it will remain at a low  
level and switch Q is turned on. The START pin  
is of high impedance and the chips power is
