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 to delay 10ms, can this be done without multiple interrupts?Assuming an 8 MHz clock
D)Refer to the CAN communication, what is the Acceptance Filter?
E)When servicing an Interrupt, the HCS12 stores PC and CPU registers in the Stack. What information does the PC register contain?
D)Answer:
Acceptance Filter?:
Communication in the CAN network is based on content-related addressing. It is not the CAN nodes that have identifiers, but rather the data and remote frames are identified (identifier — ID). So, all CAN messages can be received by every CAN node (broadcasting). Each receiver is independently responsible for selecting CAN messages. Such receiver-selective addressing is very flexible, but it requires that each receiver filters the received CAN messages (acceptance filtering).

In this lab, you will design a finite state machine to control the tail lights of an unsual car. There are three lights on each side that operate in sequence to indicate thedirection of a turn. Figure ! shows the tail lights and Figure 2 shows the flashing sequence for (a) left turns and (b) right rums.
