<p>The present invention deals with the control of a data bus (120) by a microcontroller (110), taking into account the fact that memory output drivers require a finite amount of time to electrically release the bus after an output operation. Each memory (130, 132) has an associated wait state number for selectively placing the microcontroller (110) in a wait state of variable length subsequent to a read operation and prior to the next I/O operation.</p> |
