CRE7 (Default 0x00)
Bit 7 - 3: Reserved.
Bit 2:Reset CIR Power-On function. After using CIR power-on, the software should
write logical 1 to restart CIR power-on function.
Bit 1: Invert RX Data.
= 1 Inverting RX Data.
= 0 Not inverting RX Data.
Bit 0: Enable Demodulation.
= 1 Enable received signal to demodulate.
= 0 Disable received signal to demodulate.
CRF0 (Default 0x00)
Bit 7: CHIPPME. Chip level auto power management enable.
= 0 disable the auto power management functions
= 1 enable the auto power management functions.
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.
= 1 enable the auto power management functions.
Bit 1: URAPME. UART A auto power management enable.
= 0 disable the auto power management functions.
= 1 enable the auto power management functions.
Bit 0: URBPME. UART B auto power management enable.
= 0 disable the auto power management functions.
= 1 enable 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
