Interrupt Request Output:
This active-low output signal will be asserted when the
XRT86VX38 device is requesting interrupt service from the
Microprocessor. This output pin should typically be con-
nected to the “Interrupt Request” input of the Microproces-
sor.
The Framer will assert this active "Low" output (toggles it
"Low"), to the local P, anytime it requires interrupt service.

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.
NOTES:
1.
This pin is inactive if the user has configured the
Microprocessor Interface to operate in either the
Intel-Asynchronous
or
the
Motorola-
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
XRT86VX38 device. The following table presents the three
different microprocessor types that the XRT86VX38 sup-
ports.
NOTE: These pins are internally pulled “Low” with a 50k
resistor.
