Microprocessor Interface—Chip Select Input:
The user must assert this active low signal in order to select the
Microprocessor Interface for READ and WRITE operations
between the Microprocessor and the XRT86VL34 on-chip reg-
isters and buffer/memory locations.

Microprocessor Interface—Read Strobe Input:
The exact behavior of this pin depends upon the type of Micro-
processor/Microcontroller the Framer has been configured to
operate in, as defined by the PTYPE[2:0] pins.
Intel-Asynchronous Mode - RD* - READ Strobe Input:
This input pin will function as the RD* (Active Low Read
Strobe) input signal from the Microprocessor. Once this active-
low signal is asserted, then the XRT86VL34 device will place
the contents of the addressed register (or buffer location) on
the
Microprocessor Interface Bi-directional data bus (D[7:0]).
When this signal is negated, then the Data Bus will be tri-
stated.
Motorola-Asynchronous (68K) Mode - DS* - Data Strobe:
This input pin will function as the DS* (Data Strobe) input sig-
nal.
Power PC 403 Mode - WE* - Write Enable Input:
This input pin will function as the WE* (Write Enable) input pin.
Anytime the Microprocessor Interface samples this active-low
input signal (along with CS* and WR/R/W*) also being asserted
(at a logic low level) upon the rising edge of PCLK, then the
Microprocessor Interface will (upon the very same rising edge
of PCLK) latch the
contents on the Bi-Directional Data Bus (D[7:0]) into the “tar-
get” on-chip register or buffer location within the XRT86VL34
device.
