EIM Bus Timing Parameters and Wait States

     The synchronous timing parameters for the EIM, shown in the i.MX6 D/Q data sheet in table 37, do not include adjustable signals or wait states(i.e. RADVA, RADVN, RWSC) while the asynchronous timing parameters in table 38 do.


     Does that imply that the adjustable signals ans wait states can not be used in synchronous mode?  I assume not because the reference manual mentions both synchronous and asynchronous modes when describing the signals and wait states.


     How do I include these adjustable signals and wait states in the timing shown in the data sheet for synchronous accesses?  Do I just add RADVA to WE14?
