AHB amba 5 lite - waited write transfer

Hello,

i didnt find at spec any note about the waited write transfer.

for example 

T1 : NONSEQ + write transfer  + HREADY is high

T2: HREADY dropped + HTRANS is idle - HWDATA ?

does the HWDATA have to be the right data or it can be any junk ? and only when the HREADY will rise again the HWDATA have to be the correct one ?

thank Michael
