***Notes:...
***Info:
The 82370 is a multi-function support peripheral that integrates
system functions necessary in an 80376 environment. It has eight
channels of high performance 32-bit DMA (32-bit internal, 16-bit
external) with the most efficient transfer rates possible on the 80376
bus. System support peripherals integrated into the 82370 provide
Interrupt Control, Timers, Wait State generation, DRAM Refresh
Control, and System Reset logic.
The 82370's DMA Controller can transfer data between devices of
different data path widths using a single channel. Each DMA channel
operates independently in any of several modes; Each channel has a
temporary data storage register for handling non-aligned data without
the need for external alignment logic.
1.0 FUNCTIONAL OVERVIEW
The 82370 contains several independent functional modules. The
following is a brief discussion of the components and features of the
82370. Each module has a corresponding detailed section later in this
data sheet. Those sections should be referred to for design and
programming information.
1.1 82370 Architecture
The 82370 is comprised of several computer system functions that are
normally found in separate LSI and VLSI components. These include: a
high-performance, eight-channel, 32-bit Direct Memory Access
Controller; a 20-level Programmable Interrupt Controller which is a
superset of the 82C5SA; four 16-bit Programmable Interval Timers which
are functionally equivalent to the 82C54 timers; DRAM Refresh
Controller; a Programmable Wait State Generator; and system reset
logic. The interface to the 82370 is optimized for high-performance
operation with the 80376 microprocessor.
The 82370 operates directly on the 80376 bus. In the Slave Mode, it
monitors the state of the processor at all times and acts or idles
according to the commands of the host. It monitors the address
pipeline status and generates the programmed number of wait states for
the device being accessed. The 82370 also has logic to the reset of
the 80376 via hardware or software reset requests and processor
shutdown status.
After a system reset, the 82370 is in the Slave Mode. It appears to
the system as an I/O device. It becomes a bus master when it is
performing DMA transfers.
To maintain compatibility with existing software, the registers within
the 82370 are accessed as bytes. If the internal logic of the 82370
requires a delay before another access by the processor, wait states
are automatically inserted into the access cycle. This allows the
programmer to write initialization routines, etc. without regard to
hardware recovery times.
