Clock System
Figure 6-1 presents the principal clock systems and their distribution in ATtiny4/5/9/10. All of the 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 register bits, as described in “Power Management and
Sleep Modes” on page 23. The clock systems is detailed below.

Clock Distribution
6.1
Clock Subsystems
The clock subsystems are detailed in the sections below.
6.1.1
CPU Clock – clk
CPU
The CPU clock is routed to parts of the system concerned with operation of the AVR Core. Examples of such mod-
ules are the General Purpose Register File, the System Registers and the SRAM data memory. Halting the CPU
clock inhibits the core from performing general operations and calculations.
6.1.2
I/O Clock – clk
I/O
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.
6.1.3
NVM clock - clk
NVM
The NVM clock controls operation of the Non-Volatile Memory Controller. The NVM clock is usually active simulta-
neously with the CPU clock.
