Clock status Register (CLKSTATUS)
These bits of this register are used to monitor if the chip clock source stable or not, and whether
clock switch failed. (Only support in Low Density)

Clock switching fail flag (write-protection bit)
1 = Clock switching failure
0 = Clock switching success
This bit is updated when software switches system clock source. If switch target clock
is stable, this bit will be set to 0. If switch target clock is not stable, this bit will be set to
1.
Write 1 to clear the bit to zero.

OSC22M clock source stable flag
1 = OSC22M clock is stable
0 = OSC22M clock is not stable or disabled
This is read only bit
OSC10K clock source stable flag
1 = OSC10K clock is stable
0 = OSC10K clock is not stable or disabled
This is read only bit
PLL clock source stable flag
1 = PLL clock is stable
0 = PLL clock is not stable or disabled
This is read only bit
