35 / 268 page  35 www.national.com RDPROT The RDPROT field controls the global read protection mechanism for the on-chip flash program memory. If a majority of the three RDPROT bits are clear, the flash program memory is protected against read access from the serial debug interface or an external flash programmer. CPU read access is not af- fected by the RDPROT bits. If a majority of the RDPROT bits are set, read access is allowed. WRPROT The WRPROT field controls the global write protection mechanism for the on-chip flash program memory. If a majority of the three WRPROT bits are clear, the flash program memory is protected against write access from any source and read access from the se- rial debug interface. If a majority of the WR- PROT bits are set, write access is allowed. 8.5 FLASH MEMORY INTERFACE REGISTERS There is a separate interface for the program flash and data flash memories. The same set of registers exist in both in- terfaces. In most cases they are independent of each other, but in some cases the program flash interface controls the interface for both memories, as indicated in the following sections. Table 16 lists the registers.
