CLKSET
When clock is set in programmable mode, the frequency of clock which it is inputted from the CLK_I terminal is set.
Complete establishment before pronounce.
Even if clock of which frequency is being inputted during resetting, it is OK.
As for the details of the establishment of clock, which see "about establishment of clock frequency".
CLKSET [8:0]

The value can be set to CLKSET are “000000000b", from "000110000b" to "111110010b".
If set value except for it, movement of LSI isn’t guaranteed.
Value to establish in CLKSET can be found by using the following ceremony.
CLKSET = Clock frequency[KHz] / 447.443 * 8
For example, when clock frequency is 3MHz, it becomes the following.
CLKSET = 3000 / 447.443 * 8 is about 54 = 000110110b
And, clock frequency is as follows.
Clock frequency[kHz] = 54 * 447.443 / 8 = 3020.24[kHz] = 3.02024[MHz]
