P1010RDB TWBE NAND parameter

I see that in the U-Boot support package for the P1010RDB-PB that the NAND MT29F16G08ABABAWP is used.

I noticed that the parameter TWBEis set to 0x39 = 57. Assuming the IFC clock is 100 MHz or 10ns. That would

set TWBE to 570ns. That seems to be 5 times above the maximum specified in the NAND timing (tWB) that can be from

200 to 100 ns depending on the mode. Is there a reason for that?
