Power PC 403 Mode - R/W - Read/Write Operation Iden-
tification Input:
This input pin will function as the “Read/Write Operation
Identification Input” pin.
Anytime the Microprocessor Interface samples this input
signal at a logic "High" (while also sampling the CS input
pin “Low”) upon the rising edge of PCLK, then the Micro-
processor Interface will (upon the very same rising edge of
PCLK) latch the contents of the Address Bus (A[14:0]) into
the Microprocessor Interface circuitry, in preparation for this
forthcoming READ operation. At some point (later in this
READ operation) the Microprocessor will also assert the
DBEN/OE input pin, and the Microprocessor Interface will
then place the contents of the “target” register (or address
location within the XRT86VL38 device) upon the Bi-Direc-
tional Data Bus pins (D[7:0]), where it can be read by the
Microprocessor.
