Architectural Overview
â Standard asynchronous communication bits for start, stop, and parity
â False-start-bit detection
â Line-break generation and detection
â ADC
â Single- and differential-input configurations
â Eight 10-bit channels (inputs) when used as single-ended inputs
â Sample rate of one million samples/second
â Flexible, configurable analog-to-digital conversion
â Four programmable sample conversion sequences from one to eight entries long, with
corresponding conversion result FIFOs
â Each sequence triggered by software or internal event (timers, or GPIO)
â On-chip temperature sensor
â I2C
2
â Two I C modules
â Master and slave receive and transmit operation with transmission speed up to 100 Kbps in
Standard mode and 400 Kbps in Fast mode
â Interrupt generation
â Master with arbitration and clock synchronization, multimaster support, and 7-bit addressing
mode
â GPIOs
â 21-52 GPIOs, depending on configuration
â 5-V-tolerant input/outputs
â Programmable interrupt generation as either edge-triggered or level-sensitive
â Bit masking in both read and write operations through address lines
â Can initiate an ADC sample sequence
â Programmable control for GPIO pad configuration:
⢠Weak pull-up or pull-down resistors
⢠2-mA, 4-mA, and 8-mA pad drive
⢠Slew rate control for the 8-mA drive
⢠Open drain enables
