Timer/Counter2 is a general purpose, single channel, 8-bit Timer/Counter module.
A simplified block diagram of the 8-bit Timer/Counter is shown in Figure 15-12.. For the actual
placement of I/O pins, see
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
The Power Reduction Timer/Counter2 bit, PRTIM2, in
page 49
Figure 16-1. 8-bit Timer/Counter Block Diagram
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 32 kHz Watch Crystal Independent of the I/O Clock
must be written to zero to enable Timer/Counter2 module.
