Reads return 0. Writes have no effect. 47 PM1_CNT_SSMI_ FLAG 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. 46 PM2_CNT_SSMI_ 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. 45 KEL_A20_ASMI_ 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. 44 DMA_SSMI_ 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 5.6.2.14 "Access Control DMA Request (DIVIL_AC_DMA)" on page 318.) 43 LPC_SSMI_FLAG 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 5.6.2.14 "Access Control DMA Request (DIVIL_AC_DMA)" on page 318.) 42 RSVD Reserved. Reads return 0. Writes have no effect. 41 UART2_SSMI_ FLAG 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 5.6.2.14 "Access Control DMA Request (DIVIL_AC_DMA)" on page 318.) 40 UART1_SSMI_ FLAG 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 5.6.2.14 "Access Control DMA Request (DIVIL_AC_DMA)" on page 318.) 39 PORTA_INIT_ ASMI_FLAG 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. |
