As a part of an "In application programming" I am using the following assembler code:
#pragma asm MOV R0,#14 //OSC frec MOV R1,#02H //PROGRAM DATA BYTE #pragma endasm
"I can't find the way of writing those two assembler lines in C" So don't do it, then! There's no point in struggling to write in 'C' just for the sake of it! This is definitely one of those areas where you're better off in assembler.
