Timer/Counter0 is a general purpose 8/16-bit Timer/Counter module, with two/one Output Com-
pare units and Input Capture feature.
The general operation of Timer/Counter0 is described in 8/16-bit mode. A simplified block dia-
gram of the 8/16-bit Timer/Counter is shown in
including I/O bits and I/O pins, are shown in bold. For actual placement of I/O pins, refer to
