PRELIMINARY
Notes:
33. If Port B size is word or byte, t
is referenced to the rising CLKB edge that reads the last word or byte write of the long word, respectively.
34. t
is the minimum time between a rising CLKB edge and a rising CLKA edge for IRA to transition HIGH in the next CLKA cycle. If the time between the
rising CLKB edge and rising CLKA edge is less than t
SKEW1
, then IRA may transition HIGH one CLKA cycle later than shown.
