6.1.2 SOCKET TX/RX Buffer Size Setting

Users need to define SOCKET n TX/RX buffer size by setting Sn_TX_BSR/Sn_RX_BSR before

SOCKET is opened.

SOCKET n TX/RX buffer size can be set to 0, 1, 2, 4, 8 or 16KB but the total size of TX or RX

buffer should not exceed 16KB each.

In case of, assign 2Kbytes RX/TX buffer per SOCKET

{

// set Base Address of TX/RX buffer for SOCKET n

TxTotalSize = 0;

// for check the total size of SOCKET n TX Buffer

RxTotalSize = 0;

// for check the total size of SOCKET n RX Buffer

for (n=0; n<7; n++) {
