The clock source for Timer/Counter2 prescaler is named PCK2. PCK2 is by default con-
nected to the main system clock (CK). By setting the AS2 bit in ASSR, Timer/Counter2
prescaler is asynchronously clocked from the PC6(TOSC1) pin. This enables use of
Timer/Counter2 as a Real-time Clock (RTC). When AS2 is set, pins PC6(TOSC1) and
PC7(TOSC2) are disconnected from Port C. A crystal can then be connected between
the PC6(TOSC1) and PC7(TOSC2) pins to serve as an independent clock source for
Timer/Counter2. The oscillator is optimized for use with a 32.768 kHz crystal. Applying
an external clock source to TOSC1 is not recommended.
8-bit Timer/Counter0
Figure 30 shows the block diagram for Timer/Counter0.
The 8-bit Timer/Counter0 can select clock source from CK, prescaled CK or an external
pin. In addition, it can be stopped as described in the specification for the
Timer/Counter0 Control Register (TCCR0). The overflow status flag is found in the
Timer/Counter Interrupt Flag Register (TIFR). Control signals are found in the
Timer/Counter0 Control Register (TCCR0). The interrupt enable/disable settings for
Timer/Counter0 are found in the Timer/Counter Interrupt Mask Register (TIMSK).
When Timer/Counter0 is externally clocked, the external signal is synchronized with the
oscillator frequency of the CPU. To assure proper sampling of the external clock, the
minimum time between two external clock transitions must be at least one internal CPU
clock period. The external clock signal is sampled on the rising edge of the internal CPU
clock.
The 8-bit Timer/Counter0 features both a high-resolution and a high-accuracy usage
with the lower prescaling opportunities. Similarly, the high prescaling opportunities make
the Timer/Counter0 useful for lower speed functions or exact timing functions with infre-
quent actions.
