|
+ The Direction Memory Access(EDMA) is a high-speed data transfer
|
|
+ operation. It supports data read/write between peripherals and
|
|
+ memories without using the CPU.
|
|
+ Goke EDMA Controller(EDMAC) directly transfers data between
|
|
+ a memory and a peripheral, between peripherals, or between memories.
|
|
+ This avoids the CPU intervention and reduces the interrupt handling
|
|
+ overhead of the CPU.
