Abstract
As a data bus control enable signal is set to 'H,' a PMOS turns on when a bi-directional bus is not in use (i.e., when a data bus active signal is 'L'), so that the bi-directional bus is pulled down through a pull-down resistor. When the data bus control enable signal is set to “L,” the PMOS turns off, thus holding the bi-directional bus in a high-impedance state. By setting the data bus control enable signal in accordance with the specifications of a peripheral device connected thereto, the state of the bi-directional bus can be arbitrarily set when it is inactive.
