29 / 361 page  29 4317J–AVR–08/10 AT90PWM2/3/2B/3B Figure 7-2. Clock Distribution AT90PWM2B/3B 7.1.1 CPU Clock – clk CPU The CPU clock is routed to parts of the system concerned with operation of the AVR core. Examples of such modules are the General Purpose Register File, the Status Register and the data memory holding the Stack Pointer. Halting the CPU clock inhibits the core from performing general operations and calculations. 7.1.2 I/O Clock – clk I/O The I/O clock is used by the majority of the I/O modules, like Timer/Counters, SPI, USART. 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. 7.1.3 Flash Clock – clk FLASH The Flash clock controls operation of the Flash interface. The Flash clock is usually active simul- taneously with the CPU clock. 7.1.4 PLL Clock – clk PLL The PLL clock allows the PSC modules to be clocked directly from a 64/32 MHz clock. A 16 MHz clock is also derived for the CPU.
