8.3 Context Switching
When an interrupt request is generated or when the BRKCS instruction is executed, a predetermined register
bank is selected by hardware. Context switching is a function that branches execution to a vector address stored in
advance in the register bank, while at the same time stacking the current contents of the program counter (PC) and
program status word (PSW) to the register bank.
The branch address is in a range of 0 to FFFFH.
