Description
Reserved. Reads return 0. Writes have no effect.
Power Management 1 Control Register SSMI Flag. If high, records that an SSMI was
generated on a write to PM1_CNT (ACPI I/O Offset 08h). Write 1 to clear; writing 0 has
no effect. PM1_CNT_SSMI_EN (bit 15) must be high to generate SSMI and set flag.
Power Management 2 Control Register SSMI Flag. If high, records that an SSMI was
generated on a write to PM2_CNT (ACPI I/O Offset 0Ch). Write 1 to clear; writing 0 has
no effect. PM2_CNT_SSMI_EN (bit 14) must be high to generate SSMI and set flag.
KEL Gate A20 ASMI Flag. If high, records that an ASMI was generated in the KEL due
to keyboard gate A20 signal change. Write 1 to clear; writing 0 has no effect.
KELA20_ASMI_EN (bit 13) must be high to generate ASMI and set flag.
DMA SSMI Flag. If high, records that an SSMI was generated on the 8237s during
DMA. Write 1 to clear; writing 0 has no effect. DMA_SSMI_EN (bit 12) must be high to
generate SSMI and set flag. (Also see Section 6.6.2.14 "Access Control DMA Request
(DIVIL_AC_DMA)" on page 338.)
LPC SSMI Flag. If high, records that an SSMI was generated on the LPC during DMA.
Write 1 to clear; writing 0 has no effect. LPC_SSMI_EN (bit 11) must be high to gener-
ate SSMI and set flag. (Also see Section 6.6.2.14 "Access Control DMA Request
(DIVIL_AC_DMA)" on page 338.)
Reserved. Reads return 0. Writes have no effect.
UART2 SSMI Flag. If high, records that an SSMI was generated on UART2 during
DMA. Write 1 to clear; writing 0 has no effect. UART2_SSMI_EN (bit 9) must be high to
generate SSMI and set flag. (Also see Section 6.6.2.14 "Access Control DMA Request
(DIVIL_AC_DMA)" on page 338.)
UART1 SSMI Flag. If high, records that an SSMI was generated on UART1 during
DMA. Write 1 to clear; writing 0 has no effect. UART1_SSMI_EN (bit 8) must be high to
generate SSMI and set flag. (Also see Section 6.6.2.14 "Access Control DMA Request
(DIVIL_AC_DMA)" on page 338.)
Port A INIT ASMI Flag. If high, records that an ASMI was generated in the KEL due to
an INIT on Port A (092h). Write 1 to clear; writing 0 has no effect.
PORTA_INIT_ASMI_EN (bit 7) must be high to generate ASMI and set flag.
Port A A20 ASMI Flag. If high, records that an ASMI was generated in the KEL due to
a A20 change on Port A (092h). Write 1 to clear; writing 0 has no effect.
PORTA_A20_ASMI_EN (bit 6) must be high to generate ASMI and set flag.
KEL INIT ASMI Flag. If high, records that an ASMI was generated in the KEL due to a
keyboard INIT sequence. Write 1 to clear; writing 0 has no effect. KEL_INIT_ASMI_EN
(bit 5) must be high to generate ASMI and set flag.
Power Management ASMI Flag. If high, records that an ASMI was generated in the
Power Management Logic. Write 1 to clear; writing 0 has no effect. PM_ASMI_EN (bit
4) must be high to generate ASMI and set flag.
PIC ASMI Flag. If high, records that an ASMI was generated in the Extended PIC Map-
per. Write 1 to clear; writing 0 has no effect. PIC_ASMI_EN (bit 3) must be high to gen-
erate ASMI and set flag.
KEL Emulation Event ASMI Flag. If high, records that an ASMI was generated in the
KEL due to a KEL emulation event. Write 1 to clear; writing 0 has no effect.
KEL_EE_ASMI_EN (bit 2) must be high to generate ASMI and set flag.
Shutdown ASMI Flag. If high, records that an ASMI was generated on a Shutdown
special cycle. Write 1 to clear; writing 0 has no effect. SHTDWN_ASMI_EN (bit 1) must
be high to generate ASMI and set flag.
