16. 8-bit Timer/Counter2 with PWM and asynchronous operation
Timer/Counter2 is a general purpose, single channel, 8-bit Timer/Counter module. The main
features are:
Single channel counter
Clear timer on compare match (auto reload)
Glitch-free, phase correct pulse width modulator (PWM)
Frequency generator
10-bit clock prescaler
Overflow and compare match interrupt sources (TOV2, OCF2A and OCF2B)
Allows clocking from external 32kHz watch crystal independent of the I/O clock
16.1
Overview
A simplified block diagram of the 8-bit Timer/Counter is shown in Figure 16-1. For the actual
placement of I/O pins, see “Pin configurations” on page 3. CPU accessible I/O Registers, includ-
ing I/O bits and I/O pins, are shown in bold. The device-specific I/O Register and bit locations
are listed in the “8-bit Timer/Counter register description” on page 156.
The Power Reduction Timer/Counter2 bit, PRTIM2, in “PRR0 – Power Reduction Register 0” on
page 54 must be written to zero to enable Timer/Counter2 module.
