Bit 6: CIRPME. Consumer IR port auto power management enable.
= 0 disable the auto power management functions
= 1 enable the auto power management functions.
Bit 5: MIDIPME. MIDI port auto power management enable.
= 0 disable the auto power management functions
= 1 enable the auto power management functions.
Bit 4: Reserved. Return zero when read.
Bit 3: PRTPME. Printer port auto power management enable.
= 0 disable the auto power management functions.
= 1 enable the auto power management functions.
Bit 2: FDCPME. FDC auto power management enable.
= 0 disable the auto power management functions.

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.
CRF3 (Default 0x00)
Bit 7 ~ 4: Reserved. Return zero when read.
Bit 3 ~ 0: Device's IRQ status.
