Q16. How many wait states does the 386SX PLUS have?
A. At 16MHz, the system utilizes a "1/4 wait state" architecture for memory access
and 0 wait states for ROM BIOS access on the motherboard. At 8MHz,
memory and ROM BIOS access require 1 wait state; on the expansion bus, all
memory or device requests are 1 wait state. lf additional waft states are
required, devices on the l/O channel hold the READY signal low, thus wait
states are generated until the device can respond to the CPU.
