CKSEL_REG
[1:0]
CKSEL_REG.
If the device is operating in register-based manual clock selection mode
(AUTOSEL_REG = 00), and CKSEL_PIN = 0, then these bits select which input clock
will be the active input clock. If CKSEL_PIN = 1 and AUTOSEL_REG = 00, the CS_CA
input pin continues to control clock selection and CKSEL_REG is of no consequence.
00: CKIN_1 selected.
01: CKIN_2 selected.

DHOLD
DHOLD.
Forces the part into digital hold. This bit overrides all other manual and automatic clock
selection controls.
0: Normal operation.
1: Force digital hold mode. Overrides all other settings and ignores the quality of all of the
input clocks.

SQ_ICAL
SQ_ICAL.
This bit determines if the output clocks will remain enabled or be squelched (disabled)
during an internal calibration. See Table 11 on page 25.
0: Output clocks enabled during ICAL.
1: Output clocks disabled during ICAL.
