C
Three fully programmable 16C550-type UARTs with IrDA support
Separate 16x8 transmit (TX) and 16x12 receive (RX) FIFOs to reduce CPU interrupt service
loading
Programmable baud-rate generator allowing speeds up to 3.125 Mbps
Programmable FIFO length, including 1-byte deep operation providing conventional
double-buffered interface
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
Two 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
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
21-60 GPIOs, depending on configuration
5-V-tolerant input/outputs
Programmable interrupt generation as either edge-triggered or level-sensitive
Low interrupt latency; as low as 6 cycles and never more than 12 cycles
Bit masking in both read and write operations through address lines
Pins configured as digital inputs are Schmitt-triggered.
Programmable control for GPIO pad configuration:
•
Weak pull-up or pull-down resistors
