EM4CTRL
This register is used to enter Energy Mode 4, in which the device only wakes up from an external pin reset or from a power cycle.
Energy Mode 4 is entered when the EM4 sequence is written to this bitfield.
EM2BLOCK
This bit is used to prevent the MCU to enter Energy Mode 2 or lower.
EMVREG
Control the voltage regulator in low energy modes 2 and 3.
