Overview
Timer/Counter n is a general purpose 8-/16-bit Timer/Counter module, with one/two Output
Compare units and Input Capture functionality.
ATmega8HVA/16HVA has two Timer/Counters, Timer/Counter0 and Timer/Counter1. The func-
tionality for both Timer/Counters is described below. Timer/Counter0 and Timer/Counter1 have
different Timer/Counter registers, as shown in 鈥漅egister Summary鈥� on page 175.
The Timer/Counter general operation is described in 8-/16-bit mode. A simplified block diagram
of the 8-/16-bit Timer/Counter is shown in Figure 17-1. 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 locations are
listed in the 鈥漅egister Description鈥� on page 90.
