Flowchart of Deep Software Standby Mode Operation
Figure 24.7 shows an example of flowchart of deep software standby mode operation. In this
example, reading the DPSRSTF bit determines whether a reset was generated by the RES pin or
exit from deep software standby mode, after the reset exception handling was performed.
When a reset was caused by the RES pin, deep software standby mode is entered after required
register settings.
When a reset was caused by exit from deep software standby mode, the IOKEEP bit is cleared
after the I/O ports setting. When the IOKEEP bit is cleared, the setting to avoid an undefined state
in Bφ output is also set.
In this flowchart, an interrupt source is checked by reading DPSIFR before the I/O ports setting. If
DPSIFR is read after the I/O ports setting, a source flag may be set without intention by the I/O
ports setting.
