Hi,
In the Clocking section of the reference manual, there is a description regarding the failure handling mechanism of FIRC. However, according to Table 157 in the manual, CMU_FC_4 and CMU_FC_5 are not referenced to FXOSC_CLK.
How should we interpret the highlighted portion in the first diagram?
As shown in the third diagram, when FIRC_CLK is used as the source for the system clock (CORE_CLK), AIPS_PLAT_CLK and HSE_CLK also derive from FIRC_CLK. The reference clocks for CMU_FC_4 and CMU_FC_5 are also FIRC_CLK.
2. So, if there are errors with AIPS_PLAT_CLK and HSE_CLK, does it mean that CMU_FC_4 and CMU_FC_5 cannot detect those errors?
