  • Page 35: Interrupts

    If multiple Infinity Series boards are installed they may or may not all share the same interrupt line. In order for an Infinity Series board to send interrupts to the PC, the PCI Interface circuit on the board must be programmed to enable interrupts. This is accomplished by setting bits 0 and 3 in the board's Interrupt Control/Status Register.

  • Page 36: Interrupt Initialization

    Communicating with the PC through to the PC. When the PC receives an interrupt, its Interrupt Service Routine (ISR) should check the Infinity board's receive flag to see if a message is pending (i.e. the receive flag is non-zero). It should then process the message for the board and write a 0 to the board's receive flag.

    The H.100 Bus & Clock Modes Note that on earlier boards other CT_NETREF rates were supported, but that this is not possible with the current switching chip. Submode 0 should only be chosen if there are no other boards in the system that can derive clocks from an external digital network.

  • Page 49: Clock Errors

    When an Infinity Series board is set for automatic fallback, the board will automatically switch to the secondary clock if the primary clock fails. When this occurs, the board will send an EC message indicating the failure. When the application designates a new primary master, it should send a new clock mode command to the board even though auto-fallback may have occurred.
