3.6.1 Program Execution State
In this state the CPU executes program instructions in sequence. The main program, subroutines,
and interrupt-handling routines are all executed in this state.
3.6.2 Exception-Handling State
The exception-handling state is a transient state that occurs when the CPU is reset or accepts an
interrupt. In this state the CPU carries out a hardware-controlled sequence that prepares it to
execute a user-coded exception-handling routine.
In the hardware exception-handling sequence the CPU does the following:

Notes:
1. A transition to the reset state occurs when RES goes Low, except when the chip is in the hardware standby mode.
2. A transition from any state to the hardware standby mode occurs when STBY goes Low.
Saves the program counter and condition code register to the stack (except in the case of a
reset).
Sets the interrupt mask (I) bit in the condition code register to “1.”
Fetches the start address of the exception-handling routine from the vector table.
Branches to that address, returning to the program execution state.
