Timer/Counter2 (TC2) is a general purpose, channel, 8-bit Timer/Counter module.

A simplified block diagram of the 8-bit Timer/Counter is shown below. 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 following register description. For the actual placement of I/O pins, refer to the pinout diagram.

The TC2 is enabled when the PRTIM2 bit in the Power Reduction Register (PRR0.PRTIM2) is written to '1'.
