Parameter 16: Specifies 16-bit CRC. 32: Specifies 32-bit CRC. none: Disables CRC.

Description Use the crc command to set the CRC mode.

Use the undo crc command to restore the default.

By default, 16-bit CRC is adopted.

These two commands are not available to sub-serial interfaces and synchronous/asynchronous serial interfaces operating as asynchronous interfaces.
