DMA
The DMA controller transfers data between peripheral
data registers and data space SRAM
In addition, DMA can access the entire data memory
space. The Data Memory Bus Arbiter is utilized when
either the CPU or DMA attempt to access SRAM,
resulting in potential DMA or CPU stalls.
The DMA controller supports 4 independent channels.
Each channel can be configured for transfers to or from
selected
supported by the DMA controller include:
• ECAN™
• Analog-to-Digital Converter (ADC)
• Serial Peripheral Interface (SPI)
• UART
• Input Capture
• Output Compare
