clocks need not be active at a given time. In order to reduce power consumption, the clocks to
modules not being used can be halted by using different sleep modes and power reduction reg-
ister bits, as described in
systems is detailed below.
Figure 6-1.
The clock subsystems are detailed in the sections below.
The CPU clock is routed to parts of the system concerned with operation of the AVR Core.
Examples of such modules are the General Purpose Register File, the System Registers and
the SRAM data memory. Halting the CPU clock inhibits the core from performing general opera-
tions and calculations.
The I/O clock is used by the majority of the I/O modules, like Timer/Counter. The I/O clock is
also used by the External Interrupt module, but note that some external interrupts are detected
by asynchronous logic, allowing such interrupts to be detected even if the I/O clock is halted.
The NVM clock controls operation of the Non-Volatile Memory Controller. The NVM clock is usu-
ally active simultaneously with the CPU clock.
