3.2.4The System Registers Pane

The system registers pane shows the Processor Status Register (psr), Control Registers, Region Registers (rr0-rr7), Pro- tection Key Registers (pkr0-pkr15), Data Breakpoint Registers (dbr0-dbr15), Instruction Breakpoint Registers (ibr0- ibr15), and Performance Monitor Configuration Registers ( pmc0-pmc15), in hexadecimal. Application programs have limited access to these registers. Addresses are displayed symbolically when possible. Symbolic displays are limited to sixteen characters; when more than sixteen characters are needed, the first fifteen are displayed and an asterisk (“ *”) is added to indicate that the symbolic display has been abbreviated. The iva register shown on the second text line in Figure 3-5is an example of this.

3.2.5The IA-32 Registers Pane

The IA-32 registers pane shows IA-32 registers in hexadecimal. For bit-encoded registers, the bits are named individually using their IA-32 mnemonics. If a name is displayed in uppercase, the corresponding bit is currently set, and if the name is displayed in lowercase, the bit is currently clear, as shown in Figure 3-6.
