Isochronous Transmit Interrupt Mask Register - Texas Instruments PCI7621 Data Manual

8.24 Isochronous Transmit Interrupt Mask Register

The isochronous transmit interrupt mask set/clear register enables the isochTx interrupt source on a per-channel
basis. Reads from either the set register or the clear register always return the contents of the isochronous transmit
interrupt mask register. In all cases the enables for each interrupt event align with the isochronous transmit interrupt
event register bits detailed in Table 8−17.
