10. Register Summary
This chapter provides an alphabetical listing of and bit definitions for the registers contained in the PPC440x5
core.
The registers, of five types, are grouped into several functional categories according to the processor func-
tions with which they are associated. More information about the registers and register categories is provided
in Section 2.2 Registers on page 47, and in the chapters describing the processor functions with which each
register category is associated.
10.1 Register Categories
Table 10-1 summarizes the register categories and the registers contained in each category. Italicized
register names are implementation-specific. All other registers are defined by the Book-E Enhanced
PowerPC Architecture.
