Local Interrupt Enable Register
Local Interrupt Enable Register (LIER) BAR2 (Offset $14): A 32-bit register
containing a group of interrupt enables corresponding to the status bits in LISR.
3.3.7 Network Target Data Register
Network Target Data (NTD) BAR2 (Offset $18): A 32-bit register containing the
data associated with one of the four network interrupts that will be sent to the
target (destination) node. Writing data to this register does not initiate the actual
interrupt; only writing to the Network Interrupt Command (NIC) register will do
so. The NTD register is both read and write accessible.
3.3.8 Network Target Node Register
The Network Target Node (NTN) BAR2 (Offset $1C): An 8-bit register containing
the node ID of the target (destination) node. Writing to the NTN register does not
initiate the actual network interrupt. This register is both read and write
accessible. The NTN register can be written or read with the Network Interrupt
Command Register as a single 16-bit word.
3.3.9 Network Interrupt Command Register
Network Interrupt Command (NIC) BAR2 (Offset $1D): An 8-bit register
containing a four-bit code that defines the type of network interrupt issued. See
for a definition of the possible codes. The NIC is both read and write
accessible. Only writing to the NIC register will initiate the network interrupt.
The network interrupt is transmitted in order following after all previously
written data.
