Register Description
Timer/Counter0 Control
Register – TCCR0
Timer Counter 0 – TCNT0
1006F–AVR–06/07
• Bits 7..3 - Res: Reserved Bits
These bits are reserved bits in the ATtiny11/12 and always read as zero.
• Bits 2,1,0 - CS02, CS01, CS00: Clock Select0, Bit 2,1 and 0
The Clock Select0 bits 2,1 and 0 define the prescaling source of Timer0.
Table 18. Clock 0 Prescale Select
The Stop condition provides a Timer Enable/Disable function. The CK down-divided
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
configured as an output. This feature can give the user SW control of the counting.
The Timer/Counter0 is implemented as an up-counter with read and write access. If the
Timer/Counter0 is written and a clock source is present, the Timer/Counter0 continues
counting in the timer clock cycle following the write operation.
