__selectCore

In this section:

Syntax

__selectCore(int core)

Parameters

core: The core to switch to. The cores are numbered from 0 and upwards.

Return value

int 0

For use with

The C-SPY simulator.

The C-SPY I-jet driver.

Description

Switches focus from the current core to the specified core for the duration of the macro invocation or until any next invocation of __selectCore.

Example

test ()
{
  __message "Core: ", __getSelectedCore(), " pc = ", #PC:%x, “\n”;
  __selectCore(0);
  __message "Core: ", __getSelectedCore(), " pc = ", #PC:%x, “\n”;
  __selectCore(1);
  __message "Core: ", __getSelectedCore(), " pc = ", #PC:%x, “\n”;

A typical result of the above macro would be (assuming that the original core was number 1):

Core: 1 pc = 0000213C
Core: 0 pc = 00000494
Core: 1 pc = 0000213C
