The Input Capture Register can capture the Timer/Counter value at a given external (edge trig-
gered) event on either the Input Capture pin (ICPn) or on the Analog Comparator pins
“Analog Comparator” on page
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 OCRnA Register, the ICRn Register, or by a set of fixed values. When using
OCRnA as TOP value in a PWM mode, the OCRnA 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 ICRn Register can be used
as an alternative, freeing the OCRnA 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 Timer/Counter. This 16-bit Timer/Counter is fully compatible with the earlier version
regarding:
•
•
•
The following control bits have changed name, but have same functionality and register location:
•
•
•
The following bits are added to the 16-bit Timer/Counter Control Registers:

The 16-bit Timer/Counter has improvements that will affect the compatibility in some special
cases.

PWMn0 is changed to WGMn0.
PWMn1 is changed to WGMn1.
CTCn is changed to WGMn2.
FOCnA and FOCnB are added to TCCRnA.
WGMn3 is added to TCCRnB.
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 OCRnA or ICRn Register. The assignment is dependent of the mode
of operation.
