3.4.18 Isa Option

The -misa=set option allows the instruction set to be specified for PIC18 targets. The default is the standard PIC18 instruction set, a selection that can be made explicit by using -misa=std. Alternatively, the PIC18 extended instruction set can be selected by using -misa=xinst. When used with a device that does not support the requested instruction set, the option will be ignored and a warning issued.

Note that this option will permit the assembler to check for conformance of the assembly program to the selected instruction set, but it does not instruct the device to operate with the selected instruction set. Use the XINST configuration bit to enable this in your device.
