Figure 4. Reset Timing
NOTES:
1. Holding WENA2/
LDA (WENB2/LDB) HIGH during reset will make the pin act as a second Write Enable pin. Holding WENA2/LDA (WENB2/LDB) LOW during reset will make
the pin act as a load enable for the programmable flag offset registers.
2. After reset, QA0 - QA8 (QB0 - QB8) will be LOW if
OEA (OEB) = 0 and tri-state if OEA (OEB) = 1.
3. The clocks RCLKA, WCLKA (RCLKB, WCLKB) can be free-running during reset.
Figure 5. Write Cycle Timing
NOTE:
1. tSKEW1 is the minimum time between a rising RCLKA (RCLKB) edge and a rising WCLKA (WCLKB) edge for
FFA (FFB) to change during the current clock cycle. If the time
between the rising edge of RCLKA (RCLKB) and the rising edge of WCLKA (WCLKB) is less than tSKEW1, then
FFA (FFB) may not change state until the next WCLKA (WCLKB)
edge.
