Universal Peripheral Interface
The
Universal
Peripheral
HPC46064 to be used as an intelligent peripheral to another
processor. The UPI could thus be used to tightly link two
HPC46064’s and set up systems with very high data ex-
change rates. Another area of application could be where
an HPC46064 is programmed as an intelligent peripheral to
a host system such as the Series 32000
é
microprocessor.
Figure 27 illustrates how an HPC46064 could be used as an
intelligent peripherial for a Series 32000-based application.
Interface
(UPI)
allows
the
The interface consists of a Data Bus (port A), a Read Strobe
(URD), a Write Strobe (UWR), a Read Ready Line (RDRDY),
a Write Ready Line (WRRDY) and one Address Input (UA0).
The data bus can be either eight or sixteen bits wide.
The URD and UWR inputs may be used to interrupt the
HPC46064. The RDRDY and WRRDY outputs may be used
to interrupt the host processor.
The UPI contains an Input Buffer (IBUF), an Output Buffer
(OBUF) and a Control Register (UPIC). In the UPI mode,
port A on the HPC46064 is the data bus. UPI can only be
used if the HPC46064 is in the Single-Chip mode.
