Registers
Figure 12-1. 16-bit Timer/Counter1 Block Diagram
Note:
The Timer/Counter (TCNT1), Output Compare Registers (OCR1A/B), and Input Capture Reg-
ister (ICR1) are all 16-bit registers. Special procedures must be followed when accessing the
16-bit registers. These procedures are described in the section
on page
no CPU access restrictions. Interrupt requests (abbreviated to Int.Req. in the figure) signals
are all visible in the Timer Interrupt Flag Register (TIFR1). All interrupts are individually
masked with the Timer Interrupt Mask Register (TIMSK1). TIFR1 and TIMSK1 are not shown
in the figure.
1. Refer to
112. The Timer/Counter Control Registers (TCCR1A/B) are 8-bit registers and have
Timer/Counter1 pin placement and description.
