C
FIFO trigger levels of 1/8, 1/4, 1/2, 3/4, and 7/8
Standard asynchronous communication bits for start, stop, and parity
False-start-bit detection
Line-break generation and detection
Single- and differential-input configurations
Four 10-bit channels (inputs) when used as single-ended inputs
Sample rate of one million samples/second
Flexible, configurable analog-to-digital conversion
Four programmable sample conversion sequences from one to eight entries long, with
corresponding conversion result FIFOs
Each sequence triggered by software or internal event (timers, analog comparators, PWM
or GPIO)
On-chip temperature sensor
One integrated analog comparator
Configurable for output to: drive an output pin, generate an interrupt, or initiate an ADC sample
sequence
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

Runs in Down or Up/Down mode
Output frequency controlled by a 16-bit load value
