An example of minimum delay command timing appears in
and hold timing of command, address, and write data cycles with respect to LFWE assertion are all
identical, and that the minimum cycle extends for two LCLK clock cycles.
An example of relaxed command timing is shown in
10.4.3.3.3
Instructions CW0, CW1, RBW, and RSW force FCM to observe the state of the LFRB pin, which may be
driven low by a long-latency NAND Flash operation, such as a page read. Following the issue of such
commands, FCM waits as shown in
observing LFRB before it has been properly driven low by the device, but does not preclude LFRB from
remaining high after a command. In addition, FCM samples and compares the state of LFRB on two
consecutive cycles of LCLK to filter out noise on this signal as it rises to the ready state (LFRB = 1).
