Input clock setting
The input type of the source clock is selectable.
VF pin function setting
The function for the VF pin (pin6) is selectable.
When setting the output select function, either setting 1 or setting 2 is selected to operate at the input level of
pin6 while turning the power on. Even if the input level of pin6 is changed during the operation, the operation
cannot be changed.
When setting the output select function, it is recommended to connect pin6 to Pull-up or Pull-down.
Setting 1 is selected to operate when the mode other than the output select function is set.
When setting the modulation control, the modulation function is turned on and off at the input level of pin6.
When setting the power down control, the power down control for the whole device is performed at the input
level of pin6.
