Definitions
Compatibility
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 Gen-
erator to generate a PWM or variable frequency output on the Output Compare pin (OC1A/B).
See
the Compare Match Flag (OCF1A/B) which can be used to generate an Output Compare inter-
rupt 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 4.19 “Analog Comparator” on page
tering 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 gener-
ating 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.
The following definitions are used extensively throughout the section:
The 16-bit Timer/Counter has been updated and improved from previous versions of the 16-bit
AVR
regarding:
• All 16-bit Timer/Counter related I/O Register address locations, including Timer Interrupt
• Bit locations inside all 16-bit Timer/Counter Registers, including Timer Interrupt Registers.
• Interrupt Vectors.
The following control bits have changed name, but have same functionality and register
location:
• PWM10 is changed to WGM10.
• PWM11 is changed to WGM11.
• CTC1 is changed to WGM12.
The following bits are added to the 16-bit Timer/Counter Control Registers:
• 1A and 1B are added to TCCR1A.
• WGM13 is added to TCCR1B.
The 16-bit Timer/Counter has improvements that will affect the compatibility in some special
cases.

The counter reaches the BOTTOM when it becomes 0x0000.
The counter reaches its MAXimum when it becomes 0xFFFF (decimal 65535).
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 assign-
ment is dependent of the mode of operation.
