23.3.2 Restore
of the restored PC.
R01UH0043EJ0300 Rev.3.00
Sep 30, 2010
Recovery from maskable interrupt servicing is carried out by the RETI instruction.
When the RETI instruction is executed, the CPU performs the following processing, and transfers control to the address
<1> Loads the restored PC and PSW from EIPC and EIPSW because the PSW.EP bit is 0 and the PSW.NP bit is 0.
<2> Transfers control back to the address of the restored PC and PSW.
The processing of the RETI instruction is shown below.
Note For the ISPR register, see 23.3.6 In-service priority register (ISPR).
Caution When the EP and NP bits are changed by the LDSR instruction during maskable interrupt
Remark
servicing, in order to restore the PC and PSW correctly during recovery by the RETI
instruction, it is necessary to set the EP bit back to 0 and the NP bit back to 0 using the LDSR
instruction immediately before the RETI instruction.
The solid line shows the CPU processing flow.
