S2 / M3  
M3 : When MODE is active, low active operation on 3rd Message. Internal pull-up  
& debounce existed.  
S3 [1] : In Norm mode, Start Address Bit 3.  
S3 /M4  
M4 : When MODE is active, low active operation on 4th Message. Internal pull-up  
& debounce existed.  
PLAYL /FMC1  
PLAYL : In Norm mode, low active input, Level-hold playback start to end  
addresses, debounce & internal pull-up existed. Holding PLAYL Low constantly will  
perform looping playback function from start to end addresses with insignificant  
dead time between messages regardless of sampling frequencies.  
FMC1 : When MODE is active, FMC1 , together with FMC2  
& FMC3 , setup  
various fixed-message configurations.  
E0 [1] : In Norm mode, End Address Bit 0.

Ground: Ground for negative PWM speaker driver.  
O
SP-: Negative signal of the differential Class-D PWM speaker outputs. This output,  
together with the SP+, is used to drive an 8speaker directly.  
Speaker Power Supply: Power supply for PWM speaker drivers.  
SP+: Positive signal of the differential Class-D PWM speaker outputs. This output,  
together with the SP-, is used to drive an 8speaker directly.  
Ground: Ground for positive PWM speaker driver.

Automatic Gain Control (AGC): The AGC adjusts the gain of the microphone  
preamplifier circuitry.  
MIC+ / AnaIn  
18  
I
MIC+ : Non-inverting input of the differential microphone signal.  
AnaIn : When FT is selected, the MIC+ input is configured to a single-ended  
input with 1Vp-p maximum input amplitude and feed-through to the speaker  
outputs.
