Homework Answers
- timer 1 to generate delay ---- external crystal with clock frequency 20Mhz is used as clock source (Fosc)
- count even by time 1 -- Fosc system clock source can be used by timer 1 clock source for even counter
- to generate delay we can select internal or external clock source. For example we can use Fosc instruction clock for generating delay

A)What is the maximum delay that can generated by an 8 bit Timer with a prescale divider value of 0 and a system clock frequency of 16 MHz? B) In the HCS12, port T is a bidirectional port. Write a short segment of code (C and Assembly) that illustrates how to initialize port T so that bits 7-4 may be used as outputs and bits 3-0 may be used as inputs: C)If you are using an output compare with interrupts...

Problem 1: SysTick Configuration The System Timer (SysTick) is a 24-bit timer that requires 4 steps to initialize. One of the 4 steps involves loading the RELOAD value. a) Provide in hexadecimal the range of valid RELOAD values. b) We can use SysTick to create time delays or generate periodic Interrupts. What are the two ways that interrupts generated by SysTick can be recognized by the CPU

Im building a clock using HDL system verilog and I need help implementing this instantiation method. Basically what happens is in the top module ClockCounter, positive clock edges are counted and passed into module timer using instantiation. Once the counter reaches MaxCount (59), a carry is generated which increments the minute clock. Once the minute clock reaches 59, another carry is generated which increments the hour clock. In module timer() below, I need help figuring out what variables in each...
