Other Parts Discussed in Thread: CC3200

Hi TI 工程师,

请问下cc3200 GSPI在从机模式下,进行DMA传输,其clk最大是多少?

  • 从CC3200的数据手册中可以查到:

    Table 4-11. SPI Slave Timing Parameters
    Parameter Parameter(1) Parameter Name Min Max Unit
    Number
    I1 F Clock frequency @ VBAT = 3.3 V    20 MHz
    Clock frequency @ VBAT ≤ 2.1 V            12 MHz
