Manufacturer:XILINX Description:Reset In: Sets the Program Counter to zero and resets the Interrupt Enable and HLDA flip-flops. The data and address buses and the control lines are three-stated during RESET and because of the asynchronous nature of RESET the processors internal registers and flags may be altered by RESET with unpredictable results. RESET IN is a Schmitt-triggered input, allowing connection to an R-C network for power-on RESET delay (see Figure 1). Upon power-up, RESET IN must remain low for at least 10 clock cycle after minimum VDD has been reached. For proper reset operation after the power-up duration, RESET IN should be kept low a minimum of three clock periods. The CPU is held in the reset condition as long as RESET IN is applied. |
