21.3. Function Configulation Flow
After MCU start-up, HW Processor is in SLEEP mode, after setting the configuration and enable
HWPCTL.HWPEN, HW Processor is moved to the Function mode, then each function can be set.
Once the configuration is set, it is not necessary to set again, however the following situation is occurred,
the configuration should be set again.
•
Once goes to SLEEP mode.
•
Function ("Sound Play" or "Memory Check") is changed.
•
Sound ROM Data Start Address and Sound ROM Data Size is changed.
•
Target Sound ROM Data is changed from internal Flash to external QSPI-Flash.
•
Target Sound ROM Data is changed from external QSPI-Flash to internal Flash.
•
KEYCODE is changed.
•
INTMASK is changed.
Figure 21.3.1 shows Function Configuration Flow.
