Revision 0.62
Bit 5: MOUIRQEN.
= 0
disable the generation of an
SMI
interrupt due to MOUSE's IRQ.
Bit 4: KBCIRQEN.
= 1
enable the generation of an
SMI
interrupt due to MOUSE's IRQ.
= 0
disable the generation of an
SMI
interrupt due to KBC's IRQ.
Bit 3: PRTIRQEN.
= 1
enable the generation of an
SMI
interrupt due to KBC's IRQ.
= 0
disable the generation of an
SMI
interrupt due to printer port's IRQ.
Bit 2: FDCIRQEN.
= 1
enable the generation of an
SMI
interrupt due to printer port's IRQ.
= 0
disable the generation of an
SMI
interrupt due to FDC's IRQ.
Bit 1: URAIRQEN.
= 1
enable the generation of an
SMI
interrupt due to FDC's IRQ.
= 0
disable the generation of an
SMI
interrupt due to UART A's IRQ.
Bit 0: URBIRQEN.
= 1
enable the generation of an
SMI
interrupt due to UART A's IRQ.
= 0
disable the generation of an
SMI
interrupt due to UART B's IRQ.
CRF7 (Default 0x00)
Bit 7 - 1: Reserved. Return zero when read.
Bit 0: SMI_EN.
= 1
enable the generation of an
SMI
interrupt due to UART B's IRQ.
This bit is the
SMI
output pin enable bit. When an
SMI
event is raised on the output of the
SMI
logic, setting this bit enables the
SMI
interrupt to be generated on the pin
SMI
. If this bit is
cleared, only the IRQ status bit in CRF3 is set, and no SMI interrupt is generated on the pin
SMI
.
= 0
Disable
SMI
CRFE, FF (Default 0x00)
Reserved for Winbond test.
= 1
Enable
SMI
