16.2.1 Registers
The Timer/Counter (TCNT1), output compare registers (OCR1A/B), and input capture register (ICR1) are all 16-bit registers.
Special procedures must be followed when accessing the 16-bit registers. These procedures are described in the
Section 16.3 “Accessing 16-bit Registers” on page 100. The Timer/Counter control registers (TCCR1A/B) are 8-bit registers
and have 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.
The Timer/Counter can be clocked internally, via the prescaler, or by an external clock source on the T1 pin. The clock select
logic block controls which clock source and 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 (clkT1).
The double buffered output compare registers (OCR1A/B) are compared with the Timer/Counter value at all time. The result
of the compare can be used by the waveform generator to generate a PWM or variable frequency output on the output
compare pin (OC1A/B). See Section 16.7 “Output Compare Units” on page 105. The compare match event will also set the
compare match flag (OCF1A/B) which can be used to generate an output compare interrupt request.
The input capture register can capture the Timer/Counter value at a given external (edge triggered) event on either the Input
capture pin (ICP1) or on the analog comparator pins (See Section 23. “Analog Comparator” on page 210) The input capture
unit includes a digital filtering unit (noise canceler) for reducing the chance of capturing noise spikes.
The TOP value, or maximum Timer/Counter value, can in some modes of operation be defined by either the OCR1A
register, the ICR1 register, or by a set of fixed values. When using OCR1A as TOP value in a PWM mode, the OCR1A
register can not be used for generating a PWM output. However, the TOP value will in this case be double buffered allowing
the TOP value to be changed in run time. If a fixed TOP value is required, the ICR1 register can be used as an alternative,
freeing the OCR1A to be used as PWM output.
16.2.2 Definitions
The following definitions are used extensively throughout the section.
Table 16-1. Definitions
Parameter
Definition
BOTTOM
The counter reaches the BOTTOM when it becomes 0x0000.
MAX
The counter reaches its MAXimum when it becomes 0xFFFF (decimal 65535).
TOP
The counter reaches the TOP when it becomes equal to the highest value in the count sequence.
The TOP value can be assigned to be one of the fixed values: 0x00FF, 0x01FF, or 0x03FF, or to the
value stored in the OCR1A or ICR1 register. The assignment is dependent of the mode of operation.
