4 Register Block
20
MOTOROLA
The register block can be mapped to any 2-Kbyte boundary within the standard 64-Kbyte address space
by manipulating bits REG[15:11] in the INITRG register. INITRG establishes the upper five bits of the
register block’s 16-bit address. The register block occupies the first 512 bytes of the 2-Kbyte block. De-
fault addressing (after reset) is indicated in the table below. For additional information refer to 5 Oper-
ating Modes and Resource Mapping.
