is cleared to 0, the CPU sets both the I bit and the UI bit in the condition code register to 1. Then
the CPU fetches a start address from the exception vector table and execution branches to that
address.
Figure 2.14 shows the stack after the exception-handling sequence.

In this state the bus is released to a bus master other than the CPU, in response to a bus request.
The bus masters other than the CPU are the DMA controller, the refresh controller, and an external
bus master. While the bus is released, the CPU halts except for internal operations. Interrupt
requests are not accepted. For details see section 6.3.7, Bus Arbiter Operation.
