180 / 259 page  www.national.com 180 Revision 1.1 Register Descriptions (Continued) Index F6h Second Level Power Management Status Register 3 (RC) Reset Value = 00h 7 Video Access Trap SMI Status (Read to Clear): SMI was caused by a trapped I/O access to the Video I/O Trap? 0= No; 1 = Yes. This is the second level of SMI status reporting. The top level is reported in F1BAR+Memory Offset 00h/02h[0]. SMI generation enabling is at F0 Index 82h[7]. 6 Reserved (Read Only) 5 Secondary Hard Disk Access Trap SMI Status (Read to Clear): SMI was caused by a trapped I/O access to the secondary hard disk? 0 = No; 1 = Yes. This is the second level of SMI status reporting. The top level is reported in F1BAR+Memory Offset 00h/02h[0]. SMI generation enabling is at F0 Index 83h[6]. 4 Secondary Hard Disk Idle Timer SMI Status (Read to Clear): SMI was caused by expiration of the Hard Disk Idle Timer Count Register (F0 Index ACh)? 0 = No; 1 = Yes. This is the second level of SMI status reporting. The top level is reported in F1BAR+Memory Offset 00h/02h[0]. SMI generation enabling is at F0 Index 83h[7]. 3 Keyboard/Mouse Access Trap SMI Status (Read to Clear): SMI was caused by a trapped I/O access to the keyboard or mouse? 0 = No; 1 = Yes. This is the second level of SMI status reporting. The top level is reported in F1BAR+Memory Offset 00h/02h[0]. SMI generation enabling is at F0 Index 82h[3]. 2 Parallel/Serial Access Trap SMI Status (Read to Clear): SMI was caused by a trapped I/O access to either the serial or parallel ports? 0 = No; 1 = Yes. This is the second level of SMI status reporting. The top level is reported in F1BAR+Memory Offset 00h/02h[0]. SMI generation enabling is at F0 Index 82h[2]. 1 Floppy Disk Access Trap SMI Status (Read to Clear): SMI was caused by a trapped I/O access to the floppy disk? 0 = No; 1 = Yes. This is the second level of SMI status reporting. The top level is reported in F1BAR+Memory Offset 00h/02h[0]. SMI generation enabling is at F0 Index 82h[1]. 0 Primary Hard Disk Access Trap SMI Status (Read to Clear): SMI was caused by a trapped I/O access to the primary hard disk? 0 = No; 1 = Yes. This is the second level of SMI status reporting. The top level is reported in F1BAR+Memory Offset 00h/02h[0]. SMI generation enabling is at F0 Index 82h[0]. Note: This register provides status on the Device Traps to the SMI handler. A bit set here indicates that an access occurred to the device while the trap was enabled, causing an SMI. Reading this register clears the SMI status bits. A read-only (mirror) version of this register exists at F0 Index 86h. If the value of the register must be read without clearing the SMI source (and consequently deasserting SMI), F0 Index 86h may be read instead. Table 4-15.
