11.2
Dual 12-bit autoreload timer
11.2.1
Introduction
The 12-bit Autoreload timer can be used for general-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 7 external pins:
●
Four PWM outputs
●
ATIC/LTIC pins for the Input Capture function
●
BREAK pin for forcing a break condition on the PWM outputs
11.2.2
Main features
●
Single Timer or Dual Timer mode with two 12-bit upcounters (CNTR1/CNTR2) and two
12-bit autoreload registers (ATR1/ATR2)
●
Maskable overflow interrupts
●
PWM mode
–
Generation of four independent PWMx signals
–
Dead time generation for Half bridge driving mode with programmable dead time
–
Frequency 2kHz-4MHz (@ 8 MHz fCPU)
–
Programmable duty-cycles
–
Polarity control
–
Programmable output modes
●
Output Compare mode
●
Input Capture mode
–
12-bit Input Capture register (ATICR)
–
Triggered by rising and falling edges
–
Maskable IC interrupt
–
Long range Input Capture
●
Internal/External Break control
●
Flexible Clock control
●
One Pulse mode on PWM2/3
●
Force update
