External Memory Interface (EMIF)
The EMIF component enables access by the CPU or DMA to memory ICs external to the PSoC 3/PSoC 5LP. It facilitates setup of the EMIF hardware, as well as UDBs and GPIOs as required. The EMIF can control synchronous and asynchronous memories without the need to configure any UDBs in synchronous and asynchronous modes. In UDB mode, UDBs must be configured to generate external memory control signals.
