GPMI NAND Mode
15.2 GPMI NAND Mode
The general-purpose media interface has several features to efficiently support NAND:
1240
• Individual chip select and ready/busy pins for up to eight NANDs.
• Individual state machine and DMA channel for each chip select.
• Special command modes work with DMA controller to perform all normal NAND
• Configurable timing based on a dedicated clock allows optimal balance of high NAND
functions without CPU intervention.
performance and low system power.
