Diagnostic access to the L2 data array is done through 64 bit read/writes that access a 32 bit data subblock along with the corresponding 7 bit ECC. Diag loads of the L2 data do not check the ECC, and thus cannot generate an ECC error. L2 Diagnostic Data - L2_DIAG_DATA (0xA0-0000-0000) (Count 2, Step 4194304) (Count 393216, Step 8)
