*1 : Remains set to High level if the refresh signal is disabled.
*2 : In the cycle for generating the I/O wait from a board mounted in the I/O expansion unit, the I/O wait is
allowed for a maximum period of one microsecond. At the end of that period, the cycle is forced to
terminate. If the I/O wait is set to "0wait," the I/O wait request signal is ignored.
*3 : Operates with +5V power supply of the I/O expansion unit.
