4.3.7. Extended external input selection (ETMv3.1 and later)

Enables you to enter a value for each part of the Extended External Input Selector register, inputs 1 to 4. Each part can have a value in the range 0 to 255. However, the number of inputs, the range of values supported, and the default value of each input depends on the ETM you are using. For example, the ARM implementation of the ARM1136JF-S™ processor in the CM1136 core module has two extended external inputs with values in the range zero to 20 and default values of zero. Third party ARM1136JF-S processor implementations might have a different number of external inputs.

If you enter a value outside the range supported by the ETM, an Error dialog box is displayed. The dialog box informs you of the range of values supported and the input that has the incorrect value.

Use these inputs in conjunction with setting external condition tracepoints.

Note

These inputs are supported only by ETMv3.1, and later.
