3. PULL-UP/PULL-DOWN RESISTOR
RESET, CMD, ST and CH pins have internal pull-up resistor. I6 to I0 pins do not have internal pull-
up/pull-down resistor.
When serial input option is selected, I4, I1 and I0 pins have internal pull-down resistor.
Table 3.1 Pins with Pull-up/Pull-down resistor
4. OPTIONS
In microcontroller interface mode, two option selection methods are available; i.e. the mask option
to be set at the time of manufacture of ROM data and the command option which is set by the
command setting.
In the mask option, either parallel input or serial input of commands and phrase addresses can be
selected. However, when the mask option is selected, no change can be made once the option is
selected after manufacture of ROM data.
The command option can select three items. Table 4.1 shows selectable options.

No.
Selection
If standby conversion is selected (Yes),
the MSM665X nters standby unless
the next specified phrase is input within
200 ms after voice ends.
