37 / 202 page  Chapter 4 Memory Map and Register Definition MC9S08QD4 Series MCU Data Sheet, Rev. 3 Freescale Semiconductor 37 Nonvolatile flash registers, shown in Table 4-4, are located in the flash memory. These registers include an 8-byte backdoor key that optionally can be used to gain access to secure memory resources. During reset events, the contents of NVPROT and NVOPT in the nonvolatile register area of the flash memory are transferred into corresponding FPROT and FOPT working registers in the high-page registers to control security and block protection options.
