Table 5. Instruction/Coefficient Memory Maps
*
LOWPR is an alf register bit. The Lucent Technologies development system tools can independently set the memory map.
MAP3 is not available if the secure mask-programmable option is selected.
MAP1 is set automatically during an HDS trap. The user-selected map is restored at the end of the HDS trap service routine.
