Socket Register Block

W5500 supports 8 Sockets for communication channel. Each Socket is controlled by

Socket n Register Block(when 0≤n≤7). The n value of Socket n Register can be selected

by BSB[4:0] of SPI Frame. Table 4 defines the 16bits Offset Address of registers in

Socket n Register Block.

Refer to ‘Chapter 4.2’ for more details about each register.
