SAM7X512/256/128 Summary
Embedded Flash Controller
– Embedded Flash interface, up to three programmable wait states
– Prefetch buffer, buffering and anticipating the 16-bit requests, reducing the required
wait states
– Key-protected program, erase and lock/unlock sequencer
– Single command for erasing, programming and locking operations
– Interrupt generation in case of forbidden operation
7.4
Peripheral DMA Controller
Handles data transfer between peripherals and memories
Thirteen channels
– Two for each USART
– Two for the Debug Unit
– Two for the Serial Synchronous Controller
– Two for each Serial Peripheral Interface
– One for the 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 requirements
Peripheral DMA Controller (PDC) priority is as follows (from the highest priority to the lowest):
