4.4.3.11
The eTSEC width input, shown in
Ethernet controller interface. Note that the value latched on this signal during POR is accessible through
the memory-mapped PORDEVSR (POR device status register) described in
Device Status Register (PORDEVSR).”
This input does not affect the width of the FIFO interface which is always an 8-bit FIFO interface.
4.4.3.12
The eTSEC3 width input, shown in
Ethernet controller interface 3. Note that the value latched on this signal during POR is accessible through
the memory-mapped PORDEVSR (POR device status register) described in
Device Status Register (PORDEVSR).”
The value of this configuration setting does not affect the width of the FIFO interface on eTSEC3, which
is always 8 bits.
4.4.3.13
The eTSEC1 protocol inputs, shown in
the eTSEC1 controller. Note that the value latched on these signals during POR is accessible through the
memory-mapped PORDEVSR (POR device status register) described in
Status Register (PORDEVSR).”
