Description
Used to select one of the following four types of sampling frequency. The
relationship between the master clock frequency (fOSC) and the sampling
frequency (fSAMP) is shown below. Values in parentheses denote the sampling
frequencies for fOSC = 4.096 MHz.

NAR
This input pin is used to select the condition for transition to the power-down
state.
Low level: The MSM6688 automatically goes to the power-down state,
excepting the time the record/playback operation is being
performed.
I
High level:The MSM6688 automatically goes to the standby state, instead of
the power-down state, excepting the time the record/playback
operation is being performed. In this case, the MSM6688 can be
placed in the power-down state by setting the REST pin to a high
level. If it is desired to use the built-in LPF for an external circuit,
this standby mode must be selected by applying a high level to the
PDMD pin.
Used to select the voice triggered starting that starts recording when the
I voice input exceeds the preset amplitude. A high input level on this pin
enables the voice triggered starting circuit.
O Outputs a high level while the record/playback operation is being performed.
Output pin to indicate the enable or disable state of the operation for
O specifying a phrase. When continuous ROM playback is performed, the next
phrase can be specified after verifying that the NAR pin becomes high.
