Hello community,

 

Which size of TX/RX FIFO of Ether MAC of i.MX6solo?

 

In 23.2.1.1 Ethernet MAC features, it can show simple 64bit FIFO

• Simple 64-Bit FIFO user-application interface

 

The other hands, TFWR bit in Transmit FIFO Watermark Register (ENET_TFWR),

It can set from 64bytes to 4032bytes.

 

Does it have local FIFO memory for TX/RX FIFO each in MAC module?

or

"FIFO" indicate a ring buffer on external memory addressed by ENET_RDSR and ENET_TDSR?

 

Best regards,

Ishii.
