6.15.4 XINTF Signal Alignment to XCLKOUT
For each XINTF access, the number of lead, active, and trail cycles is based on the internal clock
XTIMCLK. Strobes such as XRD, XWE0, XWE1, and zone chip-select (XZCS) change state in relationship
to the rising edge of XTIMCLK. The external clock, XCLKOUT, can be configured to be either equal to or
one-half the frequency of XTIMCLK.
For the case where XCLKOUT = XTIMCLK, all of the XINTF strobes will change state with respect to the
rising edge of XCLKOUT. For the case where XCLKOUT = one-half or one-fourth XTIMCLK, some strobes
will change state either on the rising edge of XCLKOUT or the falling edge of XCLKOUT. In the XINTF
timing tables, the notation XCOHL is used to indicate that the parameter is with respect to either case;
XCLKOUT rising edge (high) or XCLKOUT falling edge (low). If the parameter is always with respect to
the rising edge of XCLKOUT, the notation XCOH is used.
For the case where XCLKOUT = one-half or one-fourth XTIMCLK, the XCLKOUT edge with which the
change will be aligned can be determined based on the number of XTIMCLK cycles from the start of the
access to the point at which the signal changes. If this number of XTIMCLK cycles is even, the alignment
will be with respect to the rising edge of XCLKOUT. If this number is odd, then the signal will change with
respect to the falling edge of XCLKOUT. Examples include the following:
•
Strobes that change at the beginning of an access always align to the rising edge of XCLKOUT. This is
because all XINTF accesses begin with respect to the rising edge of XCLKOUT.
Examples:
•
Strobes that change at the beginning of the active period will align to the rising edge of XCLKOUT if
the total number of lead XTIMCLK cycles for the access is even. If the number of lead XTIMCLK
cycles is odd, then the alignment will be with respect to the falling edge of XCLKOUT.
Examples:
•
Strobes that change at the beginning of the trail period will align to the rising edge of XCLKOUT if the
total number of lead + active XTIMCLK cycles (including hardware waitstates) for the access is even. If
the number of lead + active XTIMCLK cycles (including hardware waitstates) is odd, then the alignment
will be with respect to the falling edge of XCLKOUT.
Examples:
•
Strobes that change at the end of the access will align to the rising edge of XCLKOUT if the total
number of lead + active + trail XTIMCLK cycles (including hardware waitstates) is even. If the number
of lead + active + trail XTIMCLK cycles (including hardware waitstates) is odd, then the alignment will
be with respect to the falling edge of XCLKOUT.
