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