2 The registers that control the flash memory (FLMCR, EBR, RAMCR, and FLMSR) are
used only in the versions with on-chip flash memory. They are not provided in the
versions with on-chip mask ROM. Reading the corresponding addresses in a mask
ROM version will always return 1s, and writes to these addresses are disabled.
