Description
Pins to determine the sampling frequency.
The sampling frequencies of 32k, 16k, 8k, and 4kHz can be selected by
combinations. (See the sampling frequencies in FUNCTIONAL
DESCRIPTION on the selection of combinations.)
Pin to test the internal circuit. Set this pin to a high level or make it open
because it has a built-in pull-up resistor.
Input pins for ADPCM data.
Pin to test the internal circuit. Make this pin open.
Pin to test the internal circuit. Make this pin open.
Ground pin
Pin to output the analog voice from the low-pass filter. Connect a 0.01
mF
capacitor to this pin. (See the AOUT connecting circuit in FUNCTIONAL
DESCRIPTION on the connecting circuit.)
Pin to output the analog voice from the DA converter.
Pins to test the internal circuit. Set these pins to a low level or make them
open because pull-down resistors are included.
This pin outputs the sampling frequency selected by the combinations of
O
S1 and S2.
The voice synthesis starts or stops by synchronizing with
VCK.
Reset pin. The voice synthesis circuit is initialized by synchronizing with

VCK.
If this pin is set to a high level, the D0 to D3 data inputs are disabled
by synchronizing with
VCK.
The AOUT and DA0 pins output 1/2 V
DD
and
become the state of no voice.

or more between
this pin and the GND pin.
