Line-break generation and detection
Three independent integrated analog comparators
Configurable for output to: drive an output pin or generate an interrupt
Compare external pin input to external pin input or to internal programmable voltage reference
Master and slave receive and transmit operation with transmission speed up to 100 Kbps in
Standard mode and 400 Kbps in Fast mode
Interrupt generation
Master with arbitration and clock synchronization, multimaster support, and 7-bit addressing
mode
Three PWM generator blocks, each with one 16-bit counter, two comparators, a PWM
generator, and a dead-band generator
One 16-bit counter

•
Flexible output control block with PWM output enable of each PWM signal
Runs in Down or Up/Down mode
Output frequency controlled by a 16-bit load value
Load value updates can be synchronized
Produces output signals at zero and load value
Comparator value updates can be synchronized
Produces output signals on match
Output PWM signal is constructed based on actions taken as a result of the counter and
PWM comparator output signals
Produces two independent PWM signals
Produces two PWM signals with programmable dead-band delays suitable for driving a
half-H bridge
Can be bypassed, leaving input PWM signals unmodified
