The Timer/Counter1 – TCNT1

ATtiny15L
• Bits 3, 2, 1, 0 – CS13, CS12, CS11, CS10: Clock Select Bits 3, 2, 1, and 0
The Clock Select bits 3, 2, 1, and 0 define the prescaling source of Timer/Counter1.
Table 11. Timer/Counter1 Prescale Select
The Stop condition provides a Timer Enable/Disable function. The prescaled CK modes
are scaled directly from the CK oscillator clock.
This 8-bit register contains the value of Timer/Counter1.
Timer/Counter1 is implemented as an up-counter with read and write access. Due to
synchronization of the CPU and Timer/Counter1, data written into Timer/Counter1 is
delayed by one CPU clock cycle.
