Two I
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
Four PWM generator blocks, each with one 16-bit counter, two comparators, a PWM generator,
and a dead-band generator
Four fault inputs in hardware to condition low-latency shutdown
One 16-bit counter

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
PWM output enable of each PWM signal
Optional output inversion of each PWM signal (polarity control)
Optional fault handling for each PWM signal
