Modify the C template code below to meet these following requirements

Pseudo-code for HW5 is shown below

Timer0 setting and variable requirements are:

16 bit counting

Triggered by SYSCLK/12

Pseudo-code for the main function of HW5 is shown below (pseudo-code for other functions is not shown)

System Initialization

Initialize Timer0

Initialize Interrupts

Repeat

Wait for keyboard to be pressed.

Reset the Timer0 count to zero

Turn Timer0 on

Wait 3 seconds

Print the number of overflows that occurred. Note, use typecasting consistent with your variable type.

Wait 1 seconds

Print the number of overflows that occurred. Note, use typecasting consistent with your variable type.

Description: Basic template for Homework 5

This program waits 3 seconds after a keyboard input and then prints the

number of overflows that occurred.
