10.10 Timer/Counter0 Prescaler
10.11 8-bit Timer/Counter Register Description

ATtiny87/ATtiny167
Figure 10-12. Prescaler for Timer/Counter0
The clock source for Timer/Counter0 is named clk
main system I/O clock clk
nously clocked from the XTAL oscillator or XTAL1 pin. This enables use of Timer/Counter0 as
a Real Time Counter (RTC).
A crystal can then be connected between the XTAL1 and XTAL2 pins to serve as an indepen-
dent clock source for Timer/Counter0.
A external clock can also be used using XTAL1 as input. Setting AS0 and EXCLK enables this
configuration.
For Timer/Counter0, the possible prescaled selections are: clk
clk
selected. Setting the PSR0 bit in GTCCR resets the prescaler. This allows the user to operate
with a predictable prescaler.
• Timer/Counter0 Control Register A – TCCR0A
• Bit 7:6 – COM0A1:0: Compare Match Output Mode A
These bits control the Output Compare pin (OC0A) behavior. If one or both of the COM0A1:0
bits are set, the OC0A output overrides the normal port functionality of the I/O pin it is con-
nected to. However, note that the Data Direction Register (DDR) bit corresponding to OC0A
pin must be set in order to enable the output driver.
