Details

The register bit SYSPLLSTS.REF_LOSTS may be incorrectly set, falsely indicating a reference clock loss.

Workaround

Do not use the PLL Reference Clock Lost Detection feature. As an alternative, use the Missing Clock Detect (MCD) feature or the Dual-Clock Comparator (DCC) to detect reference clock loss.

• For the MCD method, refer to C2000Ware example sysctl_ex1_missing_clock_detection under the sysctl folder.
• For the DCC method, refer to C2000Ware example dcc_ex4_clock_fail_detect under the dcc folder.
