Wrong works jump to the interrupt handler Timer0 Overflow.
v5.0 has no this bug.
Please check it out.
Code: Select all
program MyProject;
{ Declarations section }
//atmega8
var
w1 : sbit at portb1_bit;
w1_Direction : sbit at ddb1_bit;

Procedure Timer0Overflow_ISR(); org IVT_ADDR_TIMER0_OVF ;
begin

if pwm_w1 > pwm_tmp then

else

end;
