Counter/Timers, 16 DMA | Intel cpci borard with a intel pentuim M

•Real-Time Clock

•On-board PCI devices

Enhanced capabilities include the ability to configure each interrupt level for active high-going edge or active low-level inputs.

The cPB-4612's interrupt controllers reside in the 6300ESB device. The "Intel 855GME Chipset" topic in Appendix D provides a link to the datasheet for this device.

1.3.15 Counter/Timers

Three 8254-style counter/timers, as defined for the PC/AT, are included on the cPB-4612. Operating modes supported by the counter/timers include:

•Interrupt on count

•Frequency divider

•Software triggered

•Hardware triggered

•One shot

The cPB-4612's Counter/Timers reside in the Intel 6300ESB device. The "Intel 855GME Chipset" topic in Appendix D provides a link to the datasheet for this device.

1.3.16 DMA

Two cascaded 8237-style DMA controllers are provided on the cPB-4612 for use by the on-board peripherals.

The cPB-4612's DMA controllers reside in the Intel 6300ESB device. The "Intel 855GME Chipset" topic in Appendix D provides a link to the datasheet for this device.

1.3.17 Real-Time Clock

The real-time clock performs timekeeping functions and includes 256 bytes of general-purpose, battery- backed, CMOS RAM. Timekeeping features include an alarm function, a maskable periodic interrupt, and a 100-year calendar. The system BIOS uses a portion of this RAM for BIOS setup information.

The cPB-4612's Real-Time Clock resides in the Intel 6300ESB device. The "Intel 855GME Chipset" topic in Appendix D provides a link to the datasheet for this device.

1.3.18 Reset

The push-button reset on the cPB-4612's faceplate functions as a "Hard Reset". See Chapter 4, "Reset," for more information about reset sources for the cPB-4612.

1.3.19 Two-Stage Watchdog Timer

The watchdog timer optionally monitors system operation and is programmable for different timeout periods (from 1 microsecond to 10 minutes). It is a two-stage watchdog, meaning that it can be enabled to produce a system management interrupt (SMI) or an IRQ (APIC 1, INT 10) before it generates a Reset. Failure to strobe the watchdog timer within the programmed time period may result in an SMI, a reset request, or both. A register bit can be read to indicate if the watchdog timer caused the reset event. This watchdog timer register is not cleared on power-up, enabling system software to take appropriate action if the watchdog generated the reboot.

See Chapter 7, "Watchdog Timer," for more information, including sample code.
