14.6.8. ECC Controller Clocks

The ECC controller for each ECC-protected memory operates at the same clock frequency as its associated RAM port.

The ECC register interface, however, is in the l4_mp_clk domain. The clock source names for each ECC controller and its RAM are determined by the specific peripheral.
