Mode Selection.
Low level : Stand-alone mode
High level : Microcontroller interface mode
A high input level causes the MSM6789L to be initialized and to go into the power
down state.
Power Down. When a low level is input, the MSM6789L goes to the power down
state. Unlike the RESET pin, this pin does not force the MSM6789L to be reset.
When a Low level is applied to this pin during recording operation, the MSM6789L
is halted, and will be maintained in the power down state while PDWN is low level.
After this pin is restored to a high level, postprocessing for recording will be performed.
Oscillator Connection. When an external clock is used, input the clock through
this pin. During the power down state, this pin must be set to the ground level.
Oscillator Connection. When an external clock is used, this pin must be left
open.
MSM6789L Test. Input a low level to the TEST pin and a high level to the TEST pin.
MSM6789L Test. This pin must be left open.
These pins must be left open as they are MSM6789L test pins.
MSM6789L Test. Input a low level signal.
