16.13.6 Memory BIST Fault Injection 0
Note:
- MBFI0, BCC[0] and DCC[0] are aliases that use the same internal 32-bit register.
- This register is write-protected when CFG.MBFI=0.
- This register is not asynchronously reset, therefore it must be properly initialized before starting any MBIST operation.

Bits 31:8 – AMMSK[23:0] Address Matching Mask
Address matching address mask. Each ‘1’ at position x indicates that the byte address bit x+2 generated by the DSU AHB host during MBIST operation is "Don't Care".
Bit 7 – FTYPE Fault Type
0x0 =Stuck At 0 (STUCKAT0)
0x1 =Stuck At 1 (STUCKAT1)
Bit 6 – AMMOD Address Matching Mode
0x0 =Address match, fault injected when the masked host address matches with the masked address (ADDR).
0x1 =Always matches, fault injected every AHB access (ALWAYS).
Bits 4:0 – BIDX[4:0] Bit Index of Injected Fault
Indicates the bit position of the fault to be injected in the data read by DSU AHB host (0 to 31).
