: FDCPME. FDC auto power management enable.
= 0disable the auto power management functions.
= 1enable the auto power management functions.
: URAPME. UART A auto power management enable.
= 0disable the auto power management functions.
= 1enable the auto power management functions.
: URBPME. UART B auto power management enable.
= 0disable the auto power management functions.
= 1enable the auto power management functions.
: 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
= 1
: Reserved. Return zero when read.
These bits indicate the IRQ status of the individual device respectively. The device's IRQ
status bit is set by their source device and is cleared by writing a 1. Writing a 0 has no
effect.
: MOUIRQSTS. MOUSE IRQ status.
: KBCIRQSTS. KBC IRQ status.
: PRTIRQSTS. printer port IRQ status.
: FDCIRQSTS. FDC IRQ status.
: URAIRQSTS. UART A IRQ status.
: URBIRQSTS. UART B IRQ status.
the chip is in the sleeping state.
