To save the connections between external device and this chip, EBI supports address bus and data bus multiplex mode. And, address latch enable (ALE) signal is used to differentiate the address and data cycle. 6.5.2 Features External Bus Interface has the following functions: Supports external devices with max. 64 KB size (8-bit data width)/128 KB (16-bit data width) Supports variable external bus base clock (MCLK) which based on HCLK Supports 8-bit or 16-bit data width Supports variable data access time (tACC), address latch enable time (tALE) and address hold time (tAHD) Supports address bus and data bus multiplex mode to save the address pins Supports configurable idle cycle for different access condition: Write command finish (W2X), Read-to-Read (R2R) |
