Bus Operation – Asynchronous Interface
Asynchronous Data Output
Data can be output from a die (LUN) if it is in a READY state. Data output is supported
following a READ operation from the NAND Flash array. Data is output from the cache
register of the selected die (LUN) to DQ[7:0] on the falling edge of RE# when CE# is
LOW, ALE is LOW, CLE is LOW, and WE# is HIGH.
If the host controller is using a tRC of 30ns or greater, the host can latch the data on the
rising edge of RE# (see Figure 22 for proper timing). If the host controller is using a tRC
of less than 30ns, the host can latch the data on the next falling edge of RE# (see Fig-
ure 23 (page 33) for extended data output (EDO) timing).
Using the READ STATUS ENHANCED (78h) command prevents data contention follow-
ing an interleaved die (multi-LUN) operation. After issuing the READ STATUS EN-
HANCED (78h) command, to enable data output, issue the READ MODE (00h) command.
Data output requests are typically ignored by a die (LUN) that is busy (RDY = 0); howev-
er, it is possible to output data from the status register even when a die (LUN) is busy by
first issuing the READ STATUS or READ STATUS ENHANCED (78h) command.
