Description
Reserved
Time-out Interrupt Flag. The flag and interrupt are cleared by writing a 1 to this bit. Writing a 0 has no
effect.
0 = No interrupt request.
1 = Interrupt request due to an initial time-out.

The SWT Time-Out (SWT_TO) register contains the 32-bit time-out period. This register is read only if
either the SWT_MCR[HLK] or SWT_MCR[SLK] bits are set.
