DIVIL_GLD_MSR_SMI Bit Descriptions (Continued)
Description
Halt ASMI Flag. If high, records that an ASMI was generated on a Halt special cycle.
Write 1 to clear; writing 0 has no effect. HLT_ASMI_EN (bit 0) must be high to generate
an ASMI and set flag.
Reserved. Reads return 0. Writes have no effect.
Power Management 1 Control Register SSMI Enable. Write 1 to enable
PM1_CNT_SSMI_FLAG (bit 47) and to allow writes to PM1_CNT (ACPI I/O Offset 08h)
to generate an SSMI.
Power Management 2 Control Register SSMI Enable. Write 1 to enable
PM2_CNT_SSMI_FLAG (bit 46) and to allow writes to PM2_CNT (ACPI I/O Offset
0Ch) to generate an SSMI.
KEL Gate A20 ASMI Enable. Write 1 to enable KEL_A20_ASMI_FLAG (bit 45) and to
allow a keyboard gate A20 signal change in the KEL to generate an ASMI.
DMA SSMI Enable. Write 1 to enable DMA_SSMI_FLAG (bit 44) and to allow 8237s
during DMA to generate an SSMI.
LPC SSMI Enable. Write 1 to enable LPC_SSMI_FLAG (bit 43) and to allow the LPC
to generate an SSMI.
Reserved. Reads return 0. Writes have no effect.
UART2 SSMI Enable. Write 1 to enable UART2_SSMI_FLAG (bit 41) and to allow
UART2 to generate an SSMI.
UART1 SSMI Enable. Write 1 to enable UART1_SSMI_FLAG (bit 40) and to allow
UART1 to generate an SSMI.
Port A INIT ASMI Enable. Write 1 to enable PORTA_INIT_ASMI_FLAG (bit 39) and to
allow an INIT on Port A in the KEL to generate an ASMI.
Port A A20 ASMI Enable. Write 1 to enable PORTA_A20_ASMI_FLAG (bit 38) and to
allow an A20 change on Port A in the KEL to generate an ASMI.
KEL INIT ASMI Enable. Write 1 to enable KEL_INIT_ASMI_FLAG (bit 37) and to allow
a keyboard INIT sequence in the KEL to generate an ASMI.
Power Management ASMI Enable. Write 1 to enable PM_ASMI_FLAG (bit 36) and to
allow the Power Management Logic to generate an ASMI.
PIC ASMI Enable. Write 1 to enable PIC_ASMI_FLAG (bit 35) and to allow the
Extended PIC Mapper to generate an ASMI.
KEL Emulation Event ASMI Enable. Write 1 to enable KEL_EE_ASMI_FLAG (bit 34)
and to allow the KEL to generate an ASMI.
Shutdown ASMI Enable. Write 1 to enable SHTDWN_ASMI_FLAG (bit 33) and to
allow a Shutdown special cycle to generate an ASMI.
Halt ASMI Enable. Write 1 to enable HLT_ASMI_FLAG (bit 32) and to allow a Halt
special cycle to generate an ASMI.
