Abstract
A programmable delay circuit ( ) maximizes processor bandwidth to external peripherals by eliminating wait state addition as the only way for satisfying timing requirements. Circuit ( ) includes a programmable delay chain ( ) connected to a hysteresis circuit ( ). A processor control signal is fed into the programmable delay chain ( ) which includes at least one switch ( ) and at least one resistive element ( ) connected together. A first feedback circuit ( ) connects the output of the programmable delay chain ( ) to the input (IN ) of the first embodiment ( ) to keep the falling edge of the control signal the same without any significant added delay. The hysteresis circuit ( ) which provides a stable signal connects to an output driver ( ) for driving the processor control signal.
