XCore Soft Reset

From XCore Exchange

This page describes how to reset an XCore chip utilising software.

Any writes to the PLL Control Register (register 6 on the L and G series) cause the chip to reset and reboot, even if the value is unchanged. Access functions are provided in the xs1.h header file. For example:

#include <xs1.h>

void chipReset(void)
{
  unsigned x;
  
  read_sswitch_reg(get_core_id(), 6, x);
  write_sswitch_reg(get_core_id(), 6, x);
}

Note: This method will not cause the XC-1 Development Kit to fully reset. The program must still be reset from the XDE.
