Voice indicator output
FLAG1 is active low when voices are play-
ing. FLAG1 is also turned low when a voice
section is output. The brightness of FLAG1
varies with the volume. FLAG1 becomes a
floating output after the silence section is
output or the voice output is terminated.
End-pulse output
When the voice output is completed, the
FLAG1 pin outputs an active low pulse. The
pulse width can be programmed depending
on the customer s requirements.
The FLAG1 and FLAG2 pins are both float-
ing outputs when the chip is in the standby
state.
Volume control
The function of volume control can be set by
mask option. A code is written in the function
table for the purpose of controlling the volume
of each section output after the volume control
function is chosen. There are two volume op-
tions, namely, full range and half range.
AUD
The AUD pin is a PMOS open drain structure.
It outputs voice signals to drive a speaker
through an external NPN transistor when the
chip is active. However, the AUD pin becomes
floating when the chip is in the standby state.
The 8050 type transistor with h
FE
150 is rec-
ommended for an output driver.
