Detailed Description

Fault-injection request descriptor.

Wraps the four-step procedure on HUM page 2875 (Figure 42.2):

1. Disable ECC test mode (EC710TMC = 0x8000).
2. Drive substitute decoder data (EC710TED = substitute).
3. Enable ECC test mode (EC710TMC = 0x8080).
4. Select EC710TED as decoder input (EC710TMC = 0x8082).

The caller is responsible for the actual MBRAM read that triggers the decoder pass and surfaces the fake fault on the next ra8_cnecc_dispatch – this helper only programs the registers.

Pass one_bit_flip = true to flip exactly one bit of the configured decoder input from the previous correct value (a 1-bit SEC scenario), or false to flip two bits (a 2-bit DED scenario). The substitute value to write is fully application-defined; this descriptor stores it as substitute for traceability and the driver writes it verbatim into EC710TED.

cppcheck cannot see tests/ so it flags every member as unused.
