2.3 ALI M1523

The M1523 is a bridge between PCI and ISA bus, providing full PCI and ISA compatible functions.

The M1523 has Integrated System Peripherals (ISP) on-chip and provides advanced features in

the DMA controller. This chip contains the keyboard controller, real-time clock and IDE master

controller. This chip also supports the Advanced Programmable Interrupt controller (APIC)

interface.

One eight-byte bidirectional line buffer is provided for ISA/DMA master memory read/writes. One

32-bit wide posted-write buffer is provided for PCI memory write cycles to the ISA bus. It also

supports a PCI to ISA IRQ routing table and level-to-edge trigger transfer.

The chip has two extra IRQ lines and one programmable chip select for motherboard Plug-and-

Play functions. The interrupt lines can be routed to any of the available ISA interrupts.

The on-chip IDE controller supports two IDE connectors for up to four IDE devices providing an

interface for IDE hard disks and CD-ROMs. The ATA bus pins are dedicated to improve the

performance of IDE master.

The M1523 supports the Super Green feature for Intel and Intel compatible CPUs. It implements

programmable hardware events, software event and external switches (for suspend/turbo/ring-in).

The M1523 provides CPU clock control (STPCLKJ). The STPCLKJ can be active (low) or inactive

(high) in turn by throttling control.
