Description

32–33 IAC1US

Instruction address compare 1 user/supervisor mode.

00 AC1 debug events are not affected by MSR[PR].

01 Reserved.

10 AC1 debug events can occur only if MSR[PR] = 0 (supervisor mode).

11 AC1 debug events can occur only if MSR[PR] = 1 (user mode).

34–35 IAC1ER

Instruction address compare 1 effective/real mode.

00 AC1 debug events are based on effective address.

01 Unimplemented in the e200z3 (Book E real address compare), no match can occur.

10 AC1 debug events are based on effective address and can occur only if MSR[IS] = 0.

11 AC1 debug events are based on effective address and can occur only if MSR[IS] = 1.

36–37 IAC2US

Instruction address compare 2 user/supervisor mode.

00 AC2 debug events are not affected by MSR[PR].

01 Reserved.

10 AC2 debug events can occur only if MSR[PR] = 0 (supervisor mode).

11 AC2 debug events can occur only if MSR[PR] = 1 (user mode).

38–39 IAC2ER

Instruction address compare 2 effective/real mode.

00 AC2 debug events are based on effective address.

01 Unimplemented in the e200z3 (Book E real address compare), no match can occur.

10 AC2 debug events are based on effective address and can occur only if MSR[IS] = 0.

11 AC2 debug events are based on effective address and can occur only if MSR[IS] = 1.
