changing XFx from an input to an output
The following table defines the timing parameter for changing the XFx pin from an input pin to an output pin.
The number shown in Figure 20 corresponds with the number in the NO. column of the table below.

reset timing
RESET is an asynchronous input that can be asserted at any time during a clock cycle. If the specified timings
are met, the exact sequence shown in Figure 21 occurs; otherwise, an additional delay of one clock cycle is
possible.
The asynchronous reset signals include XF0/1, CLKX0, DX0, FSX0, CLKR0, DR0, FSR0, and TCLK0/1.
The following table defines the timing parameters for the RESET signal. The numbers shown in Figure 21
correspond with those in the NO. column of the following table.
Resetting the device initializes the bus control register to seven software wait states and therefore results in slow
external accesses until these registers are initialized.
HOLD is an asynchronous input and can be asserted during reset.
