The operating mode determines memory mapping and whether memory is addressed
on- or off-chip. Refer to Figure 4-2, which illustrates the memory maps for each of the
four modes of operation. Memory locations for on-chip resources are the same for both
expanded multiplexed and single-chip modes. 192-byte RAM is mapped to $0040 af-
ter reset. It can be placed at any other 4K boundary ($x040) by writing an appropriate
value to the INIT register. The 64-byte register block is mapped to $0000 after reset
and can also be placed at any 4K boundary ($x000) by writing an appropriate value to
the INIT register. Refer to Table 4-1, which details the MCU register and control bit
assignments.
