11.2 12-BIT AUTORELOAD TIMER 2 (AT2)
11.2.1 Introduction
The 12-bit Autoreload Timer can be used for gen-
eral-purpose timing functions. It is based on a free-
running 12-bit upcounter with an input capture reg-
ister and four PWM output channels. There are 6
external pins:
– Four PWM outputs
– ATIC pin for the Input Capture function
– BREAK pin for forcing a break condition on the
