Hiii
tell me what is the meaning of red line
__irq void Timer0ISR(void)
{
if (Timer1)
Timer1--


thanx

 

The value of Timer1 is decreased by 1...

It is the opposite of Timer1++, which increase the value of Timer1 by 1...

 

In this case it does not matter, but the decrementing of Timer1 happens AFTER the value of Timer1 is used in the expression. If the decrement operator is placed before the expression then the decrementing takes place BEFOR the expression is used.

Timer1--     // A post-decremnt operation
--Timer1     // A pre-decremnt
