Purpose Controls:
• branch prediction
• performance features
• error and parity logic.
Usage constraints The ACTLR is:
• a read/write register
• accessible in Privileged mode only
• ARM recommends that any instruction that changes bits [31:28] or
[7] is followed by an
ISB
instruction to ensure that the changes have
taken effect before any dependent instructions are executed.
Configurations Available in all processor configurations.
Attributes See Table 4-24 on page 4-41.
Figure 4-27 shows the ACTLR bit assignments.
