PRELIMINARY
Notes:
17. CSA=LOW, W/RA=HIGH, MBA=LOW. It is not necessary to program offset register on consecutive clock cycles.
18. t
is the minimum time between the rising CLKA edge and a rising CLKB for FFC/IRC to transition HIGH in the next cycle. If the time between the rising
edge of CLKA and rising edge of CLKC is less than t
SKEW1
, then FFC/IRC may transition HIGH one cycle later than shown.
