7.1.3 Determining Rp Value (DDP, QDP only)
For general operation, INT operates as normal output pin, so that tF is equivalent to tR (below 10ns). But since INT operates as open drain
with 50K ohm for Reset (Hot/Warm/NAND Flash Core) operations and ‘2X program operation(007Dh)’ case at DDP option, the pull-up resis-
tor value is related to tr(INT). And appropriate value can be obtained with the following reference charts.
