The Timer/Counter0 Control
Register – TCCR0
1187H–AVR–09/07
Figure 20. Timer/Counter0 Block Diagram
• Bits 7..3 – Res: Reserved Bits
These bits are reserved bits in the ATtiny15L and always read as zero.
• Bits 2, 1, 0 – CS02, CS01, CS00: Clock Select0, Bits 2, 1 and 0
The Clock Select0 bits 2, 1 and 0 define the prescaling source of Timer0.
Table 9. Clock 0 Prescale Select
The Stop condition provides a Timer Enable/Disable function. The prescaled CK modes
are scaled directly from the CK Oscillator clock. If the external pin modes are used for
Timer/Counter0, transitions on PB2/(T0) will clock the counter even if the pin is config-
ured as an output. This feature can give the user SW control of counting.
