Description
(Data I/O). Used to connect the DIN and DOUT pins of serial register.
44
DI/O
I/O This pin outputs the data to be written into the serial register or
inputs the data read from the serial registers.
(Data ROM). Used to connect the DOUT pin of each external serial

CS1
(Chip Select). Used to connect the CS pin of serial register and the
41
CS2
CS (CS1, CS2, CS3) pins of serial voice ROM.

This pin is used to select either the stand-alone mode or the
microcontroller interface mode.

I
Low level: Stand-alone mode
High level: Microcontroller interface mode.
A high input level to this pin causes the MSM6688 to be initialized
53
RESET
I
and to go into the power down state.
(Power Down). When a low level is input to this pin, the MSM6688
goes to the power down state. Unlike the RESET pin, this pin does
not force to reset the MSM6688. When an Low level is applied to
35
PDWN
I
this PDWN pin during recording operation, the MSM6688 is halted,
and will be maintained in the power down state while PDWN is low.
After this pin is restored to a high level, postprocessing for
recording will be performed.
Used to connect an oscillator. When an external clock is used,
47
XT
I
input the clock through this pin. At the power down state, this pin
must be set to the ground level.
48
XT
Used to connect an oscillator, when an external clock is used, this
O
pin must be left open.
34
TEST
Used to test the MSM6688. Input a low level to the TEST pin and
33
TEST
I
a high level to the TEST pin.
