Register Block
2.1 Introduction
The register block can be mapped to any 2-Kbyte boundary within the standard 64-Kbyte address space
by manipulating bits REG15–REG11 in the register initialization register (INITRG). 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.
Default addressing (after reset) is indicated in
