The Debug UART performs the following data conversions:
The i.MX28 supports off-chip DRAM storage through the EMI controller,
which is connected to the four internal AHB/AXI busses. The EMI supports
multiple external memory types, including:
Two Ethernet MAC controllers, each connected to one uDMA (unified DMA).
Supports 10/100 Mbps with TCP/UDP/IP Acceleration and IEEE 1588
Functions; also supports two RMII connectivity or one MII connectivity.
The Controller Area Network (CAN) protocol is a message based protocol
used for serial data. It was designed specifically for automotive but is also
used in industrial control and medical applications. The serial data bus runs
at 1 Mbps.
The General-Purpose Media Interface (GPMI) controller is a flexible NAND
flash controller with 8-bit data width, up to 50-MBps I/O speed and individual
chip select and DMA channels for up to 8 NAND devices. It also provides a
interface to 20-bit BCH for ECC.
The high-speed ADC block is designed to sample an analog input with 12-bit
resolution and a sample rate of up to 2 Msps. The output of the HSADC block
can be moved to the external memory through APBH-DMA. A typical user
case of the HSADC is to work with the PWM block to drive an external linear
image scanner sensor.
