I want to understand 2 points in Ethernet Switch ICs.
In this IC - LAN9353, on page 34, the description in the table is mentioned.
"A low selects 1K bits (128 x 8) through 16K bits (2K x 8). A high selects 32K bits (4K x 8) through 512K bits (64K x 8)."
Does the above indicate the size of an external EEPROM or does it indicate the size of an internal EEPROM inside the LAN9353.
Second question:
In this IC - KSZ8863, It is mentioned in that the switch can be in managed mode and unmanaged mode. Can someone tell me the difference between the two modes? What is the meaning of managed mode and unmanaged mode.
