Notes:
* 1) All the data listed above accept both reading and writing.
* 2) The data marked with "-" is invalid for writing and reset to 0 for reading.
* 3) When the PON bit is set to 1 in Control Register 2, all the bits are reset to 0 in Oscillation Adjustment
Register, Control Register 1 and Control Register 2 excluding the
XST
bit.
* 4) When DEV=0, the oscillation adjustment circuit is configured to allow correction of a time count gain
or loss up to
±
1.5ppm.
When DEV=1, the oscillation adjustment circuit is configured to allow correction of a time count gain
or loss up to or
±
0.5ppm.
* 5) PON is a power-on-reset flag.
