Hello , 

I am using TIM6 to generate 1 sec of delay and i am toggling LED gpio in the timer ISR

HCLK is 50MHz , prescalar = 999, and period = 49999



The issue is when i use below macro, i get close to 1sec. shown in the pic below



and when the that macro is not used. there is a significant difference . I want to know how exactly that macro is affecting here. i can not able to connect the dots. please help 

without above macro output
