Step 6 (Optional) Run:
crc { 16 | 32 | none }
The CRC check mode is set for the synchronous serial interface.
By default, 16-bit CRC is used.
Step 7 (Optional) Run:
idlecode { 7e | ff }
The line idle code is set for the synchronous serial interface.
By default, a synchronous serial interface uses the line idle code 0x7e.
Step 8 (Optional) Run:
mtu mtu
The MTU is set for the synchronous serial interface.
The default MTU of a synchronous serial interface is 1500 bytes.
