Notes:
46. If Port C size is word or byte, t
is referenced to the rising CLKC edge that writes the last word or byte of the long word, respectively.
47. t
is the minimum time between a rising CLKC edge and a rising CLKA edge for EFA to transition HIGH in the next CLKA cycle. If the time between the
rising CLKC edge and rising CLKA edge is less than t
SKEW1
, then the transition of EFA HIGH may occur one CLKA cycle later than shown.
