28. Power Management Controller (PMC)
28.1
6430D–ATARM–25-Mar-11
Description
The Power Management Controller (PMC) optimizes power consumption by controlling all sys-
tem and user peripheral clocks. The PMC enables/disables the clock inputs to many of the
peripherals and the Cortex-M3 Processor.
The Power Management Controller provides the following clocks:
• MCK, the Master Clock, programmable from a few hundred Hz to the maximum operating
• Processor Clock (HCLK), must be switched off when entering the processor in Sleep Mode.
• Free running processor Clock (FCLK)
• the Cortex-M3 SysTick external clock
• the USB Device HS Clock (UDPCK)
• Peripheral Clocks, typically MCK, provided to the embedded peripherals (USART, PMC, SPI,
• Programmable Clock Outputs can be selected from the clocks provided by the clock
frequency of the device. It is available to the modules running permanently, such as the
Enhanced Embedded Flash Controller.
TWI, TC, HSMCI, etc.) and independently controllable. In order to reduce the number of clock
names in a product, the Peripheral Clocks are named MCK in the product datasheet.
