Chapter 1 MC9S12NE64 Device Overview
1.5.3 Wait
This mode is entered by executing the CPU WAI instruction. In this mode, the CPU will not execute
instructions. The internal CPU signals (address and databus) will be fully static. All peripherals stay active.
For further power consumption, the peripherals can individually turn off their local clocks.
1.5.4 Run
Although this is not a low-power mode, unused peripheral modules must not be enabled in order to save
power.
1.6 Resets and Interrupts
See the exception processing section of the CPU12 reference manual for information on resets and
interrupts. System resets can be generated through external control of the RESET pin, through the clock
and reset generator module (CRG), or through the low-voltage reset (LVR) generator of the voltage
regulator module. See the CRG and VREG_PHY block description sections for detailed information on
reset generation.
