Figure 1.5.4 Saving/Restoring General-purpose Registers under Interrupt Processing
(3) Interrupt return
program counter (PC) to restarting address, during interrupt service program.
Otherwise returning interrupt causes INTATRAP again. When interrupt acceptance
processing has completed, stacked data for PC

Note: If [RETN] is executed with the above data unaltered, the program returns to the
b.
Interrupt return instructions [RETI]/[RETN] perform as follows.
As for Address Trap interrupt (INTARTAP), it is required to alter stacked data for

Using data transfer instructions
Example: Save/store register using data transfer instructions
PINTxx:
Saving/restoring general-purpose registers using PUSH/POP instruction
To save only a specific register without nested interrupts, data transfer
address trap area and INTATRAP occurs again.
