BRK instruction is the BRK instruction address plus two. Therefore,
the byte following the BRK will not be executed when the value of
the PC is returned from the BRK routine.
program is branched to the address where is specified by the inter-
rupt vector table. By testing the value of the B Flag in the PS
(pushed on the Stack) in the interrupt service routine, the user can
determine if the interrupt was caused by the BRK instruction.

When the BRK instruction is executed, the CPU pushes the
current PC contents onto the stack. The BADRS designated in
the interrupt vector table is stored into the PC.
