3.4.12. Branch Broadcast Control Register

The TRCBBCTLR characteristics are:

Purpose

Controls how branch broadcasting behaves, and enables branch broadcasting to be enabled for certain memory regions.

Usage constraints

There are no usage constraints.

Configurations

Available in all configurations.

Attributes

See the register summary in Table 3.1 and Table 3.2.

Figure 3.13 shows the TRCBBCTLR bit assignments.

[31:9]-RAZ/WI
[8]MODE

Selects mode:

0

Exclude mode. The Address Range Comparators defined by the RANGE field indicate address ranges where branch broadcasting is not enabled. Selecting no ranges results in branch broadcasting being enabled over the whole memory map.

1

Include mode. The Address Range Comparators defined by the RANGE field indicate address ranges where branch broadcasting is enabled. Setting RANGE to all zeroes is unpredictable when in Include mode.

[7:4]-RAZ/WI
[3:0]RANGESelects Address Range Comparators to control where branch broadcasting is enabled. One bit is provided for each implemented Address Range Comparator.
