Technical Summary
Operating Modes and On-Chip Memory
4.5.1 Memory Map and Register Block
The INIT register controls the location of the register block and RAM in
the 64-Kbyte central processor unit (CPU) address space. The 64-Kbyte
register block originates at $0000 after reset and can be placed at any
4-Kbyte boundary ($x000) by writing an appropriate value to the INIT
register. Since the RAM also begins at $0000 after reset, 64 bytes are
overlaid by the register block. Registers are a higher priority resource
than RAM. Therefore, the RAM which is overlaid by registers is
inaccessible. Either the registers or the RAM must be remapped to gain
access to all 512 bytes of the RAM. Refer to Figure 4-3 and Figure 4-4.

Note 1. To access the full 512 bytes of RAM, remap either the register block
or the RAM to any 4-K ($x000) boundary.
