PRELIMINARY
Notes:
19. CSA=LOW, W/RA=HIGH, MBA=LOW. It is not necessary to program offset register on consecutive clock cycles.
20. 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
, then FFC/IRC may transition HIGH one cycle later than shown.
21. It is not necessary to program offset register bits on consecutive clock cycles. FIFO write attempts are ignored until IRA is set HIGH.
22. t
is the minimum time between the rising CLKA edge and a rising CLKC 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
, then FFC/IRC may transition HIGH one cycle later than shown.
23. Programmable offsets are written serially to the SD input in the order AFA offset (Y1), AEB offset (X1), AFC offset (Y2), and AEA offset (X2).
