GENERAL DESCRIPTION
Embedded customers benefit from using the Am386 microprocessor in a number of ways. Full static operation, coupled with 3-V supplies, benefit customers who desire low-power designs. Standby Mode allows the Am386SXL/SXLV microprocessors to be clocked down to 0 MHz (DC) and retain full register contents. A float pin places all outputs in a three-state mode to facilitate board test and debug. Additionally, the Am386SXLV microprocessor comes mwith System Management Mode (SMM) for system and opower management. SMI (System Management Inter.crupt) is a non-maskable, higher priority interrupt than UNMI and has its own code space (1 Mbyte in Real and 16 Mbyte in Protected Mode). SMI can be – Fully compatible with all 386SX systems and software s System Management Mode (SMM) for system and power management (Am386SXLV only) – System Management Interrupt (SMI) for power management independent of processor operating mode and operating system – SMI coupled with I/O instruction br...
