— 4-channel 32-bit Periodic Interrupt Timer (PIT) module
— Software Watchdog Timer (SWT)
System Integration Unit (SIU) module to manage resets, external interrupts, GPIO and pad control
System Status and Configuration Module (SSCM) to provide information for identification of the device, last boot
mode, or debug status and provides an entry point for the censorship password mechanism
Clock Generation Module (MC_CGM) to generate system clock sources and provide a unified register interface,
enabling access to all clock sources
Clock Monitor Unit (CMU) to monitor the integrity of the main crystal oscillator and the PLL and act as a frequency
meter, measuring the frequency of one clock source and comparing it to a reference clock
Mode Entry Module (MC_ME) to control the device power mode, i.e., RUN, HALT, STOP, or STANDBY, control
mode transition sequences, and manage the power control, voltage regulator, clock generation and clock management
modules
Reset Generation Module (MC_RGM) to manage reset assertion and release to the device at initial power-up
Nexus development interface (NDI) per IEEE-ISTO 5001-2003 Class Two Plus standard

Low-power operation
MPC5606S devices are designed for optimized low-power operation and dynamic power management of the core processor and
peripherals. Power management features include software-controlled clock gating of peripherals and multiple power domains
to minimize leakage in low-power modes.
There are two static low-power modes, STANDBY and STOP, and two dynamic power modes—RUN and HALT. Both low
power modes use clock gating to halt the clock for all or part of the device. The STANDBY mode also uses power gating to
automatically turn off the power supply to parts of the device to minimize leakage.
STANDBY mode turns off the power to the majority of the chip to offer the lowest power consumption mode. The contents of
the cores, on-chip peripheral registers and potentially some of the volatile memory are lost. STANDBY mode is configurable
to make certain features available with the disadvantage that these consume additional current:
It is possible to retain the contents of the full RAM or only 8 KB.
