Applications - Motorola M-CORE MMC2001 Series Reference Manual

The SPROM control bit in the EIM configuration register allows selective access pro-
tection to be applied to the ROM. (See 7.7 EIM Configuration Register.) This bit
may be used to control read access to the ROM based on the state of the M•CORE
PSR(S) bit. Attempted cycles to a protected ROM address space are terminated with
a TEA response to the CPU.
