MODE
is active, l
ow active operation on 1
st
Message. Internal pull-up
& debounce existed.
S1
[1]
: In
Norm
mode, Start Address Bit 1.
M2
: When
MODE

M3
: When
MODE
is active, l
ow active operation on 3
rd
Message. Internal pull-up
& debounce existed.
S3
[1]
: In
Norm
mode, Start Address Bit 3.
M4
: When
MODE
is active, l
ow active operation on 4
th
Message. Internal pull-up
& debounce existed.
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,
various fixed-message configurations.
E0
[1]
: In
Norm
mode, End Address Bit 0.
M5
: When
MODE
is active, l
ow active operation on 5
th
Message. Internal pull-up
& debounce existed.
Analog Ground
: Ground path for analog circuits.
E1
[1]
: In
Norm
mode, End Address Bit 1.
M6
: When
MODE
is active, l

Message. Internal pull-up
& debounce existed.
E3
[1]
: In
Norm
mode, End Address Bit 3.
M8
: When

is active, l
ow active operation on 8
th
Message. Internal pull-up
& debounce existed.
Ground
: Ground for negative PWM speaker driver.
SP-
: Negative signal of the differential Class-D PWM speaker outputs. This output,
together with the SP+, is used to drive an 8
speaker 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 8
speaker directly.
Ground
: Ground for positive PWM speaker driver.
Automatic Gain Control (AGC)
: The AGC adjusts the gain of the microphone
preamplifier circuitry.
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.
