reset input pin.
At “L” level input, the device enters the initial state.
During reset input, operation of all circuits stops and it will be in a power
down state.
Input the "L" level at the time of a power supply injection. After power
supply voltage is stabilized, please make it "H" level.
CPU interface chip select pin.
A serial interface becomes effective on the "L" level.
serial clock input pin.
serial data input pin.
A DIPH pin chooses the timing which takes in serial data inside LSI.
When a DIPH pin is the "L" level, DI input data is taken in inside LSI by
the rising edge of a SCK clock.
When a DIPH pin is "H" level, DI input data is taken in inside LSI by the
falling edge of a SCK clock.
A BUSY pin outputs the signal which shows a phrase reproduction
state.
The "L" level is outputted during reproduction.
A NCR pin outputs the signal which shows the input permission state of
a command.
When the NCR pin is "H" level ,a command input is possible.
When the NCR pin is the "L" level ,a command input cannot be
performed.
Wired to a crystal or ceramic oscillator.
A feedback resistor of around 1 M Ω is built in between this XT pin and
XT pin (pin 35).
When using an external clock, input the clock from this pin.
When you use a crystal or ceramic oscillator, please connect with the
latest of LSI as much as possible.
Wired to a ceramic or crystal oscillator.
When using an external clock, keep this pin open.
When you use a crystal or ceramic oscillator, please connect with the
latest of LSI as much as possible.
Regulator output pin.
Insert a 10 µ F or larger capacitor between this pin and DGND pin.
Standard voltage output pin for 3.3V regulators.
Insert a 0.1 µ F capacitor between this pin and DGND pin.
Standard voltage output pin of built-in speaker amplifier.
Insert a 0.1 µ F or larger capacitor between this pin and AGND pin.
Analog output pin.
When you input into built-in speaker amplifier, insert a 10 µ F capacitor
between this pin and SPIN pin.
It becomes the power supply of Built-in P2ROM.
