BWSEL_REG.
Selects nominal f3dB bandwidth for PLL. See the DSPLLsim for settings. After
BWSEL_REG is written with a new value, an ICAL is required for the change to take
effect.
Reserved.
CKSEL_REG.
If the device is operating in manual register-based 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, the CKSEL[1:0] input pins continue to
control clock selection and CKSEL_REG is of no consequence.
00: CKIN_1 selected.
01: CKIN_2 selected.
10: CKIN_3 selected.
11: CKIN_4 selected.
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.
