BWSEL_REG.
Selects nominal f3dB bandwidth for PLL. See DSPLLsim for settings. After BWSEL_REG
is written with a new value, an ICAL is required for the change to take effect.
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.
This bit determines if the output clocks will remain enabled or be squelched (disabled)
during an internal calibration. See Table 8 on page 20.
0: Output clocks enabled during ICAL.
1: Output clocks disabled during ICAL.
