7-36 System Registers
TLIOINTRn—I/O Interrupt Registers
Table 7-17 TLI/OINTR Register Bit Definitions
To post an interrupt, the I/O port writes the TLI/OINTR register appropri-
ate for its node with the desired IPL(s) and the targeted CPUs.
These registers appear in TLSB broadcast space. Writes that address
these locations are accepted without regard to receiver node ID. This
