1394A PCI PHY/Link Open Host Controller Interface
Internal Registers
(continued)
Interrupt Event Register
The interrupt event set/clear register reflects the state of the various FW322 interrupt sources. The interrupt bits
are set by an asserting edge of the corresponding interrupt signal or by writing a 1 in the corresponding bit in the
set register. The only mechanism to clear the bits in this register is to write a 1 to the corresponding bit in the clear
register. This register is fully compliant with OHCI, and the FW322 adds OHCI 1.0 compliant vendor-specific
interrupt function to bit 30. When reading the interrupt event register, the return value is the bitwise AND function
of the interrupt event and interrupt mask registers per the 1394 Open Host Controller Interface Specification.
