Figure 18-1. 16-bit Timer/Counter Block Diagram
The Timer/Counter (TCNTn) Output Compare Registers (OCRnA/B/C) and Input
Capture Register (ICRn) are all 16-bit registers. Special procedures must be followed
when accessing the 16-bit registers. These procedures are described in the section
"Accessing 16-bit Registers" on page
(TCCRnA/B/C) are 8-bit registers and have no CPU access restrictions. Interrupt
requests (shorten as Int.Req.) signals are all visible in the Timer Interrupt Flag Register
(TIFRn). All interrupts are individually masked with the Timer Interrupt Mask Register
(TIMSKn). TIFRn and TIMSKn are not shown in the figure since these registers are
shared by other timer units.
The Timer/Counter can be clocked internally, via the prescaler or by an external clock
source on the Tn pin. The Clock Select logic block controls which clock source and
which clock edge the Timer/Counter uses to increment (or decrement) its value. The
Timer/Counter is inactive when no clock source is selected. The output from the clock
select logic is referred to as the timer clock (clk
The double buffered Output Compare Registers (OCRnA/B/C) are compared with the
