NOTE:
1. The EFI input LOW and HIGH times as shown are required to guarantee the CLK LOW and HIGH times shown.
FIGURE 9. CLK AS A FUNCTION OF EFI
NOTE:
1. This is an asynchronous input. The setup and hold times shown are required to guarantee the response shown.
FIGURE 10. RESET AND READY TIMING AS A FUNCTION OF RES WITH S1, S0, ARDY + ARDYEN, AND SRDY + SRDYEN HIGH
NOTES:
1. This is an asynchronous input. The setup and hold times shown are required to guarantee the response shown.
2. If SRDY + SRDYEN or ARDYEN are active before and/or during the first bus cycle after RESET, READY may not be deasserted until the
falling edge of
