CRF3 (Default 0x00)
Bit 7 - 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 7 : Reserved.
Bit 6 : Reserved.
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 6 - 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 a1. Writing a 0 has no effect.
Bit 6 :Reserved
Bit 5 : HMIRQSTS. Hardware monitor IRQ status.
Bit 4 : WDTIRQSTS. Watch dog timer IRQ status.
Bit 3 Reserved
Bit 1 : IRQIN1STS. IRQIN1 status.
Bit 0 : IRQIN0STS. IRQIN0 status.
CRF6 (Default 0x00)
Bit 7 - 0 _{: Enable bits of the SMI / PME generation due to the device's IRQ.}
Bit 7
Bit 6
These bits enable the generation of an SMI / PME interrupt due to any IRQ of the
devices. SMI / PME logic output = (MOUIRQEN and MOUIRQSTS) or (KBCIRQEN and
KBCIRQSTS) or (PRTIRQEN and PRTIRQSTS) or (FDCIRQEN and FDCIRQSTS)
or (URAIRQEN and URAIRQSTS) or (URBIRQEN and URBIRQSTS) or
(HMIRQEN and HMIRQSTS) or (WDTIRQEN and WDTIRQSTS) or
(IRQIN3EN and IRQIN3STS) or (IRQIN2EN and IRQIN2STS) or
