options wcb4xxp te_nt_override= 0xE7 to set port 4 and 5 as NT mode.
The method is : 1111 1111 ---> oxFF ---> TE mode(default vaule). If you would like to set the port(s) as NT mode. Just switch the corresponding bit from 1 to 0(start it from the right side to the left)
For example, let's take span 3 and 6 for an example. 11011011( the third bit and the sixth bit), then transfer the 8 bits binary to hexadecimal. 1101 1011(binary)<----> oxDB(hexadecimal)
