Publication Release Date: Nov. 2000
- 128 - Revision 0.60
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 - 0
: Devices' trap status.
CRF3 (Default 0x00)
Bit 7 - 6
: Reserved. Return zero when read.
Bit 5 - 0
: Device's IRQ status.
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.
Bit 5
: MOUIRQSTS. MOUSE IRQ status.
Bit 4
: KBCIRQSTS. KBC IRQ status.
Bit 3
: PRTIRQSTS. printer port IRQ status.
Bit 2
: FDCIRQSTS. FDC IRQ status.
Bit 1
: URAIRQSTS. UART A IRQ status.
Bit 0
: URBIRQSTS. UART B IRQ status.
CRF4 (Default 0x00)
Bit 7
: Reserved. Return zero when read.
Bit 4 - 0
: These bits indicate the IRQ status of the individual GPIO function or logical device
respectively. The status bit is set by their source function or device and is cleared by
writing a 1. Writing a 0 has no effect.
Bit 6
: SCIRQSTS. Smart Card interface IRQ status.
Bit 5
: Reserved. Return zero when read.
Bit 4
: WDTIRQSTS. Watch dog timer IRQ status.
Bit 3
: CIRIRQSTS. Consumer IR IRQ status.
Bit 2
: MIDIIRQSTS. MIDI IRQ status.
Bit 1
: IRQIN1STS. IRQIN1 status.
Bit 0
: IRQIN0STS. IRQIN0 status.
