NOTES:
1. tSKEW1 is the minimum time between a rising RCLK edge and a rising WCLK edge to guarantee that
FF will go HIGH during the current clock cycle. If the time between the rising edge
of RCLK and the rising edge of WCLK is less than tSKEW1, then
FF may not change state until the next WCLK edge.
2. Select this mode by setting (
FL, RXI, WXI) = (0,0,0), (0,1,1), (1,0,0) or (1,1,1) during Reset.
NOTES:
1. Single device mode (
FL, RXI, WXI) = (0,0,0), (0,0,1), (0,1,0), (1,0,0), (1,0,1) or (1,1,0). FL, RXI, WXI should be static (tied to VCC or GND).
2. The clocks (RCLK, WCLK) can be free-running asynchronously or coincidentally.
3. After reset, the outputs will be LOW if
OE = 0 and tri-state if OE = 1.
