In the last line of the following paragraph of BF-548 Technical reference Rev 1.0  August 2010, the statement ARDY is "sampled asserted" should rather be "sampled de-asserted"


The  ARDY input is treated as an asynchronous input, however it must reach the desired value (either asserted or deasserted) more than one  SCLK cycle before the schedule d rising edge of AWE  or  ARE . This determines whether the access is extended or not. Once the transaction is extended by the assertion of  ARDY, the transaction completes in the cycle after ARDY is sampled asserted.
