*2) The data marked with “–” is invalid for writing and reset to 0 for reading.
*3) When the XSTP bit is set to 1 in control register 2, all the bits are reset to 0 in oscillation adjustment register 1, control register 1 and control register 2
excluding the XSTP bit.
*4) Writing to the oscillation adjustment register requires zero filling the (0) bit.
