4.3 Security
The MCU security feature allows the the protection of the on chip Flash and EEPROM memory. For a
detailed description of the security features refer to the S12X9SEC block guide.
4.4 Low Power Modes
The microcontroller features three main low power modes. Consult the respective Block Guide for
information on the module behavior in Stop, Pseudo Stop, and Wait Mode. An important source of
information about the clock system is the Clock and Reset Generator Block Guide (CRG).
4.4.1 Stop Mode
Executing the CPU STOP instruction stops all clocks and the oscillator thus putting the chip in fully static
mode. Wake up from this mode can be done via reset or external interrupts.
4.4.2 Pseudo Stop Mode
This mode is entered by executing the CPU STOP instruction. In this mode the oscillator is still running
and the Real Time Interrupt (RTI) or Watchdog (COP) sub module can stay active. Other peripherals are
turned off. This mode consumes more current than the full STOP mode, but the wake up time from this
mode is significantly shorter.
4.4.3 Wait Mode
This mode is entered by executing the CPU WAI instruction. In this mode the CPU will not execute
instructions.TheinternalCPUsignals(addressanddatabus)willbefullystatic.Allperipheralsstayactive.
For further power consumption the peripherals can individually turn off their local clocks.
4.4.4 Run Mode
Although this is not a low power mode, unused peripheral modules should not be enabled in order to save
power.
