GPIO Signals
INTREQ is an input for IDE style XIO. It may be connected to any available GPIO. This signal is then routed to the TM5250
VIC interrupt controller. Or any of the direct interrupt lines can be used. See interrupt assignments in

Interfacing to a NAND-Flash involves both hardware setup and software support. The
hardware support is designed to be very flexible in supporting the standard devices
plus extensions that may be provided by some flash vendors.
recommended settings for the hardware configured for various NAND-Flash
operations.
A NAND transaction may consist of 0, 1, or 2 command phases and 0, 1, 2, 3 or 4
address phases, and n data phases. The sequence is as follows: first command, low
address (address bits [7:0]), middle address (address bits [16:8]), high address
