DMA Controller
Acting as one Matrix Master
Embeds 4 channels:
– 3 channels with 8 bytes/FIFO for Channel Buffering
– 1 channel with 32 bytes/FIFO for Channel Buffering
Linked List support with Status Write Back operation at End of Transfer
Word, HalfWord, Byte transfer support.
Handles high speed transfer of SPI, SSC and HSMCI (peripheral to memory, memory to
peripheral)
Memory to memory transfer
Can be triggered by PWM and T/C which enables to generate waveforms though the
External Bus Interface
The DMA controller can handle the transfer between peripherals and memory and so receives
the triggers from the peripherals listed below. The hardware interface numbers are also given in
7.7
Peripheral DMA Controller
Handles data transfer between peripherals and memories
Nineteen channels
Two for each USART
Two for the UART
Two for each Two Wire Interface
One for the PWM
One for each Analog-to-digital Converter
Low bus arbitration overhead
– One Master Clock cycle needed for a transfer from memory to peripheral
– Two Master Clock cycles needed for a transfer from peripheral to memory
Next Pointer management for reducing interrupt latency requirement
