Time Base Timer Control Register
buzzer drive. Divider output is from DVO pin.
Divider Output (DVO)
Approximately 50% duty pulse can be output using the divider output circuit, which is useful for piezoelectric
(0036H)
Note:Selection of divider output frequency (DVOCK) must be made while divider output is disabled (DVOEN="0").

Configuration
Control
The Divider Output is controlled by the Time Base Timer Control Register.
Also, in other words, when changing the state of the divider output frequency from enabled (DVOEN="1") to
disable(DVOEN="0"), do not change the setting of the divider output frequency.
