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 trig-
gered) event on either the Input Capture pin (ICP1) or on the Analog Comparator pins

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.
The following definitions are used extensively throughout the section:
Table 16-1.
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.

PWM10 is changed to WGM10.
PWM11 is changed to WGM11.
CTC1 is changed to WGM12.
FOC1A and FOC1B are added to TCCR1C.
WGM13 is added to TCCR1B.
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 Regis-
ter. The assignment is dependent of the mode of operation.
