Interrupt Requests
4 Interrupts
RX_THRESH (3PGSWRXTHR0) – Receive Threshold interrupt
(nonpaced)
RX (3PGSWRXINT0) – Receive interrupt (paced)
TX (3PGSWTXINT0) – Transmit interrupt (paced)
Misc (3PGSWMISC0) – Other interrupts
All Ethernet Switch interrupts go to MPU Subsystem and PRU-
ICSS.
The Subsystem contains 3 sets of interrupts C0, C1, and C2 to
allow for split core processing of packets. On this device, only
the C0 version of the interrupts is used.
DMA Requests
None
Physical Address
L4 Fast slave port
L3 Fast initiator port
