Timer/Counter Clock Sources
Counter Unit
Compatibility
The 16-bit Timer/Counter has been updated and improved from previous versions of 16-bit AVR
Timer/Counters. 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 backward compatibility in some spe-
cial cases.
The Timer/Counter can be clocked by an internal or an external clock source. The clock source
is selected by the Clock Select logic which is controlled by the Clock Select (CS12:0) bits
located in the Timer/Counter control Register B (TCCR1B). For details on clock sources and
prescaler, see
The main part of the 16-bit Timer/Counter is the programmable 16-bit bi-directional counter unit.
