+ 0x100n)][0x0000]
As this value is internally calculated with the values of Sn_RX_RD and Sn_RX_WR, it is
automatically changed by RECV command of SOCKET n Command Register(Sn_CR) and
receives data from the remote peer. When reading this register, the user should read the
upper byte(0xFE4026, 0xFE4126, 0xFE4226, 0xFE4326, 0xFE4426, 0xFE4526, 0xFE4626,
Sn_RX_RSR (SOCKET n RX Received Size Register)[R][(0xFE4026 + 0x100n) – (0xFE4027
It informs the user of the byte size of the received data in Internal RX Memory of SOCKET n.
