Kinetis FlexBus ALE

I have a K64 FlexBus connected to an FPGA in multiplexed mode.  In AN4393, "Using FlexBus Interface for Kinetis Microcontrollers," Figure 1, which FB_CLK edge should I use to latch the address (while ALE is high, of course)?  The falling edge (near the middle of ALE)?  Or the rising edge (near the end of ALE)?
