Write a C program to toggle only the PORTB.4 bit continuously every two seconds Use Timer1, Normal mode, and 1:1024 prescaler to create the delay. Assume XTAL = 10 MHz. XTAL= 10 MHz ==> us=Tclock Tprescaler+clock = us Tdelay= number of tick in decimal (no decimal points, round up) = #include void T1Delay : int main() DDRB = OxFF; while (1) PORTBA= (1 us=Tclock Tprescaler+clock = us Tdelay= number of tick in decimal (no decimal points, round up) = #include void T1Delay : int main() DDRB = OxFF; while (1) PORTBA= (1
