General-Purpose Media Interface(GPMI)
15.1 General-Purpose Media Interface Overview
This chapter describes the general-purpose media interface.
The GPMI controller is a flexible interface to up to eight NAND Flash with configurable
address and command behavior, providing support for future devices not yet specified. The
GPMI resides on the APBH and provides an interface to the 20-bit BCH module to allow
direct parity processing.
Registers are clocked on the HCLK domain. The I/O and pin timing are clocked on a
dedicated GPMICLK domain. GPMICLK can be set to maximize I/O performance.
The following figure shows a block diagram of the GPMI controller.
