i.MX28 Product Features
1.3.23 UARTs
There are six UARTs (similar to 16550 UART) provided; five for application use and one
for debug. The application UARTs are high-speed devices capable of running up to 3.25
Mbits per second with 16-byte receive and transmit FIFOs. The application UARTs support
DMA and flow control (RTS/CTS). The debug UART does not use DMA channels.

1.3.24 Low-Resolution ADC, Touch-Screen Interface and
The LRADC provides 16 physical channels of 12-bit resolution for analog-to-digital
conversion. Only eight "virtual" channels can be used at one time, but those eight channels
can be mapped to any of the 16 physical channels. Some physical channels have dedicated
inputs:
The USB_DN/DP inputs can only be sampled with the LRADC in non-USB mode (see
HW_USBPHY_CTRL_DATA_ON_LRADC).
The remaining seven channels are available for other uses and can be used for resistive
button sense, touch-screens or other analog input. Channels 0 and 1 have integrated drivers
for external temperature monitor thermistors. Channels 2–6 have integrated drivers for
resistive touch-screens. The LRADC provides typical performance of 12-bit
no-missing-codes, 9-bit SNR, and 1% absolute accuracy (limited by the bandgap reference).
