4.14.5.7 Camera Parallel Port
The fast camera parallel port interfaces with a variety of external image sensors, stores the image data in
a FIFO, and generates DMA requests. The camera parallel port supports 8 bits.
Figure 4-21 shows the timing diagram for the camera parallel port.

4.14.5.8 UART
The CC3220x device includes two UARTs with the following features:
• Programmable baud-rate generator allowing speeds up to 3 Mbps
• Separate 16-bit × 8-bit TX and RX FIFOs to reduce CPU interrupt service loading
• Programmable FIFO length, including a 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
• Generation and detection of line-breaks
