Overview
Timer/Counter0 and Timer/Conter1 are general purpose Timer/Counter modules with two inde-
pendent Output Compare Units, each, and with PWM support. They allow accurate program
execution timing (event management) and wave generation.
Register and bit references in this section are written in general form. A lower case “n” replaces
the Timer/Counter number, and a lower case “x” replaces the Output Compare Unit, in this case
Compare Unit A or Compare Unit B. However, when using the register or bit defines in a pro-
gram, the precise form must be used, i.e., TCNT0 for accessing Timer/Counter0 counter value
and so on.
A simplified block diagram of the 8-bit Timer/Counter is shown in Figure 12-1 on page 80. For
the actual placement of I/O pins, refer to Figure 1-1 on page 2. CPU accessible I/O Registers,
including I/O bits and I/O pins, are shown in bold. The device-specific I/O Register and bit loca-
tions are listed in the “Register Description” on page 92.
