17.3.2 Restore
of the restored PC.
Recovery from maskable interrupt servicing is carried out by the RETI instruction.
When the RETI instruction is executed, the CPU performs the following steps, and transfers control to the address
<1> Loads the restored PC and PSW from EIPC and EIPSW because the EP bit of the PSW is 0 and the NP bit
<2> Transfers control to the address of the restored PC and PSW.
The following illustrates the processing of the RETI instruction.
Note For the ISPR register, see 17.3.6 In-service priority register (ISPR).
Caution When the PSW.EP bit and the PSW.NP bit are changed by the LDSR instruction during
Remark
of the PSW is 0.
maskable interrupt servicing, in order to restore the PC and PSW correctly during recovery by
the RETI instruction, it is necessary to set PSW.EP back to 0 and PSW.NP back to 0 using the
LDSR instruction immediately before the RETI instruction.
The solid line shows the CPU processing flow.
