标题: [M480] PDMA ExSRAM Basic Mode [打印本页] 作者: admin 时间: 2022-8-12 15:48 标题: [M480] PDMA ExSRAM Basic Mode Application: M480 EBI interface write/read data to External SRAM with PDMA basic mode example code.
BSP Version: M480 Series BSP CMSIS V3.03.001
Hardware: NuMaker-PFM-M487 V3.0 & M487 Advance Ver4.0
This chip is equipped with an external bus interface (EBI) for external device use. In order to connect between an external device and a chip, EBI is operating at address bus and data bus multiplex mode. The EBI supports three chip selects that can connect three external devices with different timing setting requirements. This example code uses M480 EBI interface to access external SRAM with PDMA on the NuMaker-PFM-M487 V3.0 board.
