RST_REG.
Internal Reset.
0: Normal operation.
1: Reset of all internal logic. Outputs tristated or disabled during reset.
ICAL.
Start an Internal Calibration Sequence.
For proper operation, the device must go through an internal calibration sequence. ICAL
is a self-clearing bit. Writing a one to this location initiates an ICAL. The calibration is
complete once the LOL alarm goes low. A valid stable clock (within 100 ppm) must be
present to begin ICAL.
Note: Any divider, CLKINn_RATE or BWSEL_REG changes require an ICAL to take effect.
0: Normal operation.
1: Writing a "1" initiates internal self-calibration. Upon completion of internal self-
calibration, ICAL is internally reset to zero.

Changes in SFOUTn_REG, PD_CKn, or DSBLn_REG will cause a random change in skew
until an ICAL is completed.
