53 / 232 page  SoC Guide — MC9S08RG60/D Rev 1.10 Freescale Semiconductor 53 MC9S08RC/RD/RE/RG Figure 4-7 FLASH Protection Register (FPROT) FPOPEN — Open Unprotected FLASH for Program/Erase 1 = Any FLASH location, not otherwise block protected or secured, may be erased or programmed. 0 = Entire FLASH memory is block protected (no program or erase allowed). FPDIS — FLASH Protection Disable 1 = No FLASH block is protected. 0 = FLASH block specified by FPS2:FPS0 is block protected (program and erase not allowed). FPS2:FPS1:FPS0 — FLASH Protect Size Selects When FPDIS = 0, this 3-bit field determines the size of a protected block of FLASH locations at the high address end of the FLASH (see Table 4-8). Protected FLASH locations cannot be erased or programmed. Bit 7 6 54321 Bit 0 Read: FPOPEN FPDIS FPS2 FPS1 FPS0 000 Write: (1) NOTES: 1. Background commands can be used to change the contents of these bits in FPROT.
