VRC4375 System Controller
Ordering
Information
Y PCI Interface
Master and target capabilities
Host bridge and add-on board modes
PCI bus arbiter with programmable arbitration scheme
Programmable arbitration scheme for PCI/CPU accessed to memory
Big-endian or little-endian byte ordering modes
4-word (16-byte) bidirectional PCI master FIFO (CPU is PCI bus master)
8-word (32-byte) bidirectional PCI target FIFO (memory is PCI bus target)
33 MHz PCI bus clock rate
132 MB/s burst transfers
Interrupt support for add-on board mode
3.3 V inputs; 5 V-tolerant inputs/outputs
Y DMA Controller
Four highly robust DMA channels
CPU-initiated block transfers between memory and PCI bus
8-word (32-byte) bidirectional DMA FIFO
Sophisticated, programmable DMA channel arbitration priority scheme
Four sets of DMA control registers for chained transfers
Next address pointer in each channel to support scatter/gather operation
Programmable DMA arbitration priority
Bidirectional unaligned transfers
Transfers at maximum PCI bandwidth of 132 MB/s
Y Interrupt Controller
Nonmaskable interrupt and interrupt signals (NMI# and INT#)
Maskable interrupt-causing events
Y UART
NY16550L Universal Asynchronous Receiver/Transmitter
Modem control functions
Separate receiver and transmitter FIFOs (16 bytes each)
Even-, odd- or no-parity bit generation
Fully prioritized interrupt control
Y Timers
One 32-bit loadable watchdog timer that generates a nonmaskable interrupt
Two 32-bit loadable general-purpose timers that generate interrupts
Highly sophisticated timers with programmable clock, start/stop, auto reload/
restart, and enable/disable interrupt bits
