2.17.1 ERRADDR Register may Read as ‘0’ when PB-Bridge-B (PB2_CLK) is Not Equal to System Clock (SYS_CLK)

If PB2_CLK is not equal to System Clock (sys_clk), ERRADDR register read will not return the failing address (caused by Single Bit Error/Dual Bit Error); instead it may return ‘0’.

Work Around:

When using RAM ECC in the application, configure PB2_CLK to be equal to SYS_CLK without any divisions.
