CKOUT Always On.
This will bypass the SQ_ICAL function. Output will be available even if SQ_ICAL is on
and ICAL is not complete or successful. See Table 4 on page 46.
0: Squelch output until part is calibrated (ICAL).
1: Provide an output. Note: The frequency may be significantly off until the part is cali-
brated.
Reserved.
Bypass Register.
This bit enables or disables the PLL bypass mode. Use only when the device is in VCO
freeze or before the first ICAL. Bypass mode is not supported for CMOS output clocks.
0: Normal operation
1: Bypass mode. Selected input clock is connected to CKOUT buffers, bypassing PLL.
