// A union that describes the entries of the vector table.  The union is needed
// since the first entry is the stack pointer and the remainder are function
// pointers.
//
// Normally the vectorTable below would require entries such as:
//   { .topOfStack = x },
//   { .ptrToHandler = y },
// But since ptrToHandler is defined first in the union, this is the default
// type which means we don't need to use the full, explicit entry.  This makes
// the vector table easier to read because it's simply a list of the handler
// functions.  topOfStack, though, is the second definition in the union so
// the full entry must be used in the vectorTable.

// existing address table... this will provide the best compatibility with
// any existing code which may utilize the tables, and which may not be able to 
// be updated to understand a new format (example: bootloader which reads the 
// application address table)
