Microprocessor Clock Input:
This clock input signal is only used if the Microprocessor
Interface has been configured to operate in the Synchro-
nous Modes (e.g., Power PC 403 Mode). If the Micropro-
cessor Interface is configured to operate in this mode, then
it will use this clock signal to do the following.
1.
To sample the CS, WR/R/W, A[14:0], D[7:0], RD/DS
and DBEN input pins, and
2.
To update the state of the D[7:0] and the RDY/
DTACK output signals.

:
1.
The Microprocessor Interface can work with
PCLK frequencies ranging up to 33MHz.
2.
This pin is inactive if the user has configured the
Microprocessor Interface to operate in either the
Intel-Asynchronous
Asynchronous Modes. In this case, the user
should tie this pin to GND.
When DMA interface is enabled, the PCLK input pin is also
used by the T1/E1 Framer to latch in or latch out receive or
output data respectively.

Microprocessor Type Input:
These input pins permit the user to specify which type of
Microprocessor/Microcontroller to be interfaced to the
XRT86VL38 device. The following table presents the three
different microprocessor types that the XRT86VL38 sup-
ports.
