PCI Bus Signals
lt_tsr[11..0] Output – Local target transaction status register. The lt_tsr [ 11..0]
bus carries several signals which can be monitored for the
transaction status. Refer to
Table 3–8 .
lirqn Input Low Local interrupt request. The local-side peripheral device
asserts
lirqn to signal a PCI bus interrupt. Asserting this
signal forces the PCI MegaCore function to assert the intan
signal for as long as the lirqn signal is asserted and the
int_dis bit (bit 10 of the command register) is 0.
