11.2 DUAL 12-BIT AUTORELOAD TIMER 3 (AT3)
11.2.1 Introduction
The 12-bit Autoreload Timer can be used for gen-
eral-purpose timing functions. It is based on one or
two free-running 12-bit upcounters with an input
capture register and four PWM output channels.
There are 6 external pins:
– Four PWM outputs
– ATIC/LTIC pin for the Input Capture function
– BREAK pin for forcing a break condition on the
