INTP (Interrupt Pin): This register contains information pertaining to the PCI/X interrupt
pin being driven. This register is read-only from the PCI/X configuration space, and may be
written at any time from within the Combined Register Group.
the INTP field are read only from within the CRG register group and which bits are both read
and write.
Table 49: CRG Space Type
This Tsi148 is a single function device and is limited by the PCI Local Bus Specification
(Revision 2.2) to only driving INTA_. In special cases, this Tsi148 can be programmed to
drive any one of the four PCI/X interrupts.
This register may be modified to show which of the four interrupt lines is being driven. The
recommended encoding of this field is shown in
