Description
No. The phase-locked loop (PLL) circuitry has an internal path to VCCINT. Connecting the VCC_CKLK pin to another voltage souce outside the VCCINT range
will damage the PLL circuitry and may also affect other functionality within the device.
Please ensure that the VCC_CKLK pin is connected to VCCINT and that all other connections are made within the specifications.
