Alice has taken over a Coldfire-based design from Bob. (Bob was promoted.) The starting address of RAM is 0x8000_0000. The starting address of Flash is 0xC000_0000 and the ending address is 0xC007_FFFF. The starting address of the peripherals (IPS in Coldfire notation) is 0x0000_0000. The vector base register is 0xC001_C000.

What is the location of the Divide by Zero exception vector?

Is the table of exception vectors found in RAM or in Flash?

What is the size of Flash memory?

If the RAM is 128KB, what is the ending address of RAM?

With what values are RAMBAR, FLASHBAR, and IPSBAR programmed?

Describe the memory map of the processor. (See Table 2.2 in the book for an example.) That is, prepare a table that shows the lowest address, highest address, and overall size of both Flash and RAM, and the lowest address of IPS.
