The timing for read data transfers is shown in
enable its output drivers and drive valid read data while LFRE is held low. FCM samples read data on the
rising edge of LFRE, which follows an optional number of wait states. Note that FCM will delay the first
read if a RBW or RSW instruction is issued, in which case LFRB sample timing takes effect (see
