16-bit Timer/Counter1
Features
Overview
The 16-bit Timer/Counter unit allows accurate program execution timing (event management),
wave generation, and signal timing measurement. The main features are:

Many register and bit references in this section are written in general form.
A simplified block diagram of the 16-bit Timer/Counter is shown in
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
• A lower case “n” replaces the Timer/Counter number, in this case 1. However, when using the
• A lower case “x” replaces the Output Compare unit channel, in this case A or B. However,
• A lower case “i” replaces the index of the Output Compare output pin, in this case U, V, W or
