CRF1 (Default 0x00)
Bit 7 : WAK_STS. This bit is set when the chip is in the sleeping state and an enabled resume
event occurs. Upon setting this bit, the sleeping/working state machine will transition the
system to the working state. This bit is only set by hardware and is cleared by writing a 1
to this bit position or by the sleeping/working state machine automatically when the global
standby timer expires.
= 0 The chip is in the sleeping state.
= 1 The chip is in the working state.
Bit 6 - 5 : Devices' trap status.
Bit 4 : Reserved. Return zero when read.
Bit 3 - 0 : Devices' trap status.
