The PRU-ICSS MII_RT module supports:
- Two MII ports
- Each MII port has:
- 32-byte RX L1 FIFO
- 64-byte RX L2 buffer
- 96-byte TX L1 FIFO
- Rate decoupling on TX L1 FIFO
- Configurable pre-amble removal on RX L1 FIFO and insertion on TX L1 FIFO
- Configurable TX L1 FIFO trigger (10 bits with 40 ns ticks)
- MII port multiplexer per direction to support line/ring structure
- Link detection through RX_ERR
- Cyclic redundancy check (CRC)
- CRC32 generation on TX path
- CRC32 checker on RX path
