network interrupts are pending, examine bits 07, 02, 01 and 00 in the LISR
register.

3.3.12 Interrupt 2 Sender Data FIFO

Interrupt 2 Sender Data FIFO (ISD2) BAR2 (Offset $28): A 32‐bit FIFO functioning
just like ISD1, except it responds only to type 2 network interrupts.

3.3.13 Interrupt 2 Sender ID FIFO

Interrupt 2 Sender ID FIFO (SID2) BAR2 (Offset $2C): An 8‐bit FIFO functioning
just like SID1, except it responds only to type 2 network interrupts.

3.3.14 Interrupt 3 Sender Data FIFO

Interrupt 3 Sender Data FIFO (ISD3) BAR2 (Offset $30): A 32‐bit FIFO functioning
just like ISD1, except it responds only to type 3 network interrupts.

3.3.15 Interrupt 3 Sender ID FIFO

Interrupt 3 Sender ID FIFO (SID3) BAR2 (Offset $34): An 8‐bit FIFO functioning
just like SID1, except it responds only to type 3 network interrupts.

3.3.16 Interrupt 4 Sender Data FIFO

Interrupt 4 Sender Data FIFO (ISD4) BAR2 (Offset $38): A 32‐bit FIFO functioning
just like ISD1, except it responds only to type 4 network interrupts.

3.3.17 Interrupt 4 Sender ID FIFO

Interrupt 4 Sender ID FIFO (SID4) BAR2 (Offset $3C): An 8‐bit FIFO functioning
just like SID1, except it responds only to type 4 network interrupts.
