above.
From this C compiler to another C compiler
• An interrupt function can be used as an ordinary function by deleting its specification with the #pragma
vect, #pragma interrupt directive.
• When an ordinary function is to be used as an interrupt function, change the program according to the
specifications of each compiler.
