All specifications are the same as listed in the Motorola M68360 User's Manual,
Chapter 10, except for the following. The superscript numbers refer to the
footnotes in the Motorola manual. The characteristics depend on whether AS, DS,
R/W and CLK01 are buffered. You can control this buffering when you configure
the emulator (see your emulator user interface manual).
