9.7. De-Selecting Interrupt Sources
The power-fail (VDD Monitor) reset is automatically enabled after every power-on reset. The software reset is
enabled after every device reset, regardless of the reset source. The RSTEN register can be used to prevent either
of these two reset sources from generating a device reset.
Register 14. RSTEN: Reset Enable Register
