1. Place the device in disable state by writing ‘00’ to NOM and DEV_EN bits of the MCTL register.
2. Keep all inputs stable high (2.7V for 3.3V and 4.4V for 5V supply) or stable low (0.3V for 3.3/5V supply).
3. The clock-input pin, CLKIN, may remain active during disable state since it is blocked internally.
