5 Operating Control and Status
5.2 Error and Status Registers
5.2.1 Clock Errors
5.2.1.1 Transient Clock Errors Registers
The transient clock error registers are used in conjunction with the watchdog EN registers and indicate error status
for H-bus clocks and DPLL1/DPLL2 sync inputs whose watchdogs are enabled. The transient indicators are
dynamic in nature; if a clock is in error only for a short time and then recovers, the error indication is deasserted
when the clock recovers. Additionally, an APLL1 out-of-lock indicator is provided, and used in conjunction with the
failsafe clocking mode. For more details, please see Section 6.7.1 on page 64 and Section 6.7.2 on page 70.
