Local Register Setting Area
A 2K-byte area of data memory, 0200H–09FFH, is the local register setting area.
The local register is specified by LRB low-order 8 bits (LRBL) in 8-byte units.
Figure 3-4 shows the map of the local register setting area.

ROM Window Setting Area
The 56K (57344)-byte area from 2000H to FFFFH in the data memory space of the
MSM66591 is not allocated as data memory. However, this area is used by the ROM
window function if set by the ROM window setting register.
The 52K (53248)-byte area from 3000H to FFFFH in the data memory space of the
MSM66591 is not allocated as data memory. However, this area is used by the ROM
window function if set by the ROM window setting register.
Corresponding to the specified area (MSM66591: 2000H and above, ML66592: 3000H
and above) of data memory, the ROM window function enables instructions to access
(read operation) data in the program space at the same address instead of data in the
data memory space.
There are two conditions for the ROM window function to be valid, (1) register settings
(ROMWIN) must enable the ROM window function, and (2) the accessed address (read
operation) must be in external data memory area.
