Two 82C37A DMA controllers (types A, B, and F)
Two 82C59A interrupt controllers
One 82C54 counter/timer
Routes external PCI interrupts to a software-selectable interrupt channel
PCI Revision 2.1 compliant
PCI clock frequencies up to 33 MHz at 5V
Supports delayed completion for ISA cycles
Active address decoding for internal I/O devices
Subtractive decoding for ISA bridge, KBC and RTC
Supports disconnection (with retry) for slow internal accesses to improve latency
Short PCI bus ownership when mastering to minimize overall system latency
Fast DMA transfers from I/O devices to PCI agents as a master
Separate request and grant signals for ISA DMA and IDE controllers
Full implementation of a standard ISA bus
Separate ISA and IDE data buses reduce noise and increase system performance
Synchronous PCI-to-ISA interface with direct drive for 5 ISA slots
Support for BIOS ROM or PowerPC systems boot ROM
Support for flash EPROM
Provides keyboard controller connections
Provides real-time clock connections
Provides data buffer control
Port B support
Port 92 support
- 32-bit addressing allows use of alternate CPUs, such as PowerPC
- supports multiple 8-bit and 16-bit scatter/gather DMA channels
- all IRQ inputs may be programmed for edge or level sensitivity
