The Restart Operation From The Stop2 Mode; Figure 1.3 Stop2 Mode Restart Operation Flow - Toshiba TXZ+ Series Reference Manual

1.3.3.3. The restart operation from the STOP2 mode

The restart operation flow from STOP2 mode release factor interrupt generating is as follows.
Check reset flag (Note1)

STOP2 release interrupt
Interrupt processing

Setting for interrupt enable register,
interrupt priority register.

Check the STOP2 release factor.
Re-setting of register (Note2)

Re-setting each function register with
register initialization.
Relase the port keep function

Initial setting at the return of STOP2,
re-setting the port setting register.

[RLMSHTDNOP]<PTKEEP> = 0
(possible to control a port.)
Note1: When STOP2 mode is released by RESET_N pin, as for a reset flag, both "STOP2 reset flag" and "reset
pin flag" are materialized.
Note2: When STOP2 mode is released by LVD reset, as for a reset flag, both "STOP2 reset flag" and "reset pin
flag" are materialized.
Note3: Register reset area is differ depending on the releasing STOP2 mode by an interrupt and the releasing
STOP2 mode by the reset of RESET_N pin or LVD. Refer to "3.2.7.1. A reset factor and the reset
initialized range" for register reset area by each factor.
Generate release factor
[RLMRSTFLGx] = xx (it is checked by which factor reset has
occured.)

Return to the NORMAL mode with all
register initialized.
Re-setting of register (Note2)

Re-setting each function register with
register initialization.
