### `#pragma _CONFIGxy value` (Deprecated)

Note: This pragma is deprecated, but still supported. Please use the «`config`» pragma, as described in the next section.

This pragma allows to specify the device configuration bits.

must be a configuration register number ( ) and must be either `H` or `L`.

Config bits values are not processed by compiler, but directly passed to assembler, so you can use here constants not defined at C level, but defined in the `<processor>.inc` file. For this reason, you cannot use here the '`_`' character as field separator.

A program containing more than one `_CONFIGxy` pragma with different values will have an unpredictable behaviour.
