EXAMPLE:The following C program shows the use of the LART functions.
Program description:
This program generates a PWM signal with a 10KHz frequency and with a 30% Duty cycle and
toggles an LED every second (Fcpu=8MHz ).
/* Program start */
#include "ST7lib_config.h"
/* prototype declaration */
void LART_OVF_IT_Routine(void);
void main(void);

LART is enabled. If the same functions are called in the
main Tree and the interrupt Tree, the function Re-entrant error
occurs in case COSMIC compiler is used with models other than
stack models.
For configuring the port pins,I/O library is used.
