STANDARD CLOCK GENERATOR WITH PLL FREQUENCY SYNTHESIZER
3. Dummy trigger generating command
The internal status of sync clock generator becomes un-
stable and a stable sync clock output (CKO) is not obtained
after the power is turned on, after a reset is cleared or after
an internal VCO oscillator frequency is set. To obtain a stable
sync clock output, enter a trigger signal from the TR input af-
ter VCO oscillator becomes stable, or enter a dummy trigger
generating command from the MCU. The PLL synthesizer
oscillator frequency after the cancellation of a reset depends
on a default (See the register configuration).
Set the command for address (A1, A0) = (1, 1).
Description
The command must be stored two times continuously when a dummy trigger is generated.
For the first time, set the dummy trigger generating command with D0=1.
For the second time, set the dummy trigger generating command with D0=0.
The second setting becomes a sync edge and a clock begins to be output from CKO.
After the first setting, CKO is in the halt state.
