6.3.2.4 High-Speed Built-In RC Oscillation Mode Operation
For the high-speed built-in RC oscillation, the oscillation start/stop can be controlled by the frequency control
register 1 (FCON1).
Oscillation can be started by setting the ENOSC bit of FCON1 to "1". OSCLK starts to be supplied after the
built-in RC oscillation clock is counted to 512 after the oscillation starts. In the low-speed crystal oscillation
mode or external clock input mode, high-speed built-in oscillation starts after the low-speed clock is counted to
26.
The high-speed clock generation circuit stops oscillation when it shifts to the STOP mode by software. By
releasing the stop mode by an external interrupt, the low-speed built-in RC oscillation clock is counted to 29 and
then the high-speed built-in RC oscillation clock is counted to 512, then the built-in RC oscillation clock is
supplied as OSCLK.
Refer to Chapter 4 “Power Management” for the operation at each power down mode.
Figure 6-12 shows the operation waveforms of the high-speed clock generation circuit in the built-in RC
oscillation mode.
