Block Protection Word, Write only | Texas Instruments MSP50C614

Memory Organization: RAM and ROM

The protection modes are implemented on the C614 as follows. Within the ROM is a dedicated storage for the block protection word (address 0x7FFE). The block protection word is divided into two 6-bit fields and two single-bit fields. The remainder of the 17-bit word is broken into three single-bit fields which are reserved for future use.

TM :	True Protection Marker (NTM)	GP : Global Protection (0 value protects)
FM :	False Protection Marker (NFM)	BP : Block Protection (0 value protects)
R :	Reserved for future use (must be 1)	1 : Default value of cells on erasure

The two 6-bit fields are designated as the true protection marker, (TM5 through TM0) and the false protection marker, (FM5 through FM0). When setting up a partition for partial ROM protection, the address of the partition must be spe- cified as:
