External Bus Interface General Control Register
| ExtEN | EBI Enable This bit is the functional enable bit for EBI. 0 = EBI function is disabled 1 = EBI function is enabled |
| ExtBW16 | EBI data width 16 bit This bit defines if the data bus is 8-bit or 16-bit. 0 = EBI data width is 8 bit 1 = EBI data width is 16 bit |
| MCLKDIV | External Output Clock Divider The frequency of EBI output clock is controlled by MCLKDIV. MCLKDIV Output clock (MCLK) 000 HCLK/1 001 HCLK/2 010 HCLK/4 011 HCLK/8 100 HCLK/16 101 HCKL/32 11X default Notice: Default value of output clock is HCLK/1 |
| ExttALE | Expand Time of ALE The ALE width (tALE) to latch the address can be controlled by ExttALE. tALE = (ExttALE + 1) * MCLK |
