Timer Interrupt Flow code V4 AVR

Have tried to use the Timer0 Overflow interrupt on V4 AVR

Under properties even if you select any of the clock sources the interupt Parameters remained grayed out and do not change

If you run V4 for PIC this behaves as you would expect ie the interrupt frequency is not grayed out and it changes as you select different clock options

Please advise what the issue is with V4 AVR or what i am doing wrong

The missing interrupt frequency calculation is caused by an omission from a file used for each AVR device.

This only affects the displayed calculation and does not prevent the interrupt from operating.

The details are described at the link below (along with a replacement file for the ATmega324P).
