Preliminary Technical Data

SPI Port—Slave Timing

SPI0, SPI1, and SPI2

Table 51 and Figure 21 describe SPI port slave operations. Note that

• In dual-mode data transmit, the SPIx_MOSI signal is also an output.

• In quad-mode data transmit, the SPIx_MOSI, SPIx_D2, and SPIx_D3 signals are also outputs.

• In dual-mode data receive, the SPIx_MISO signal is also an input.

• In quad-mode data receive, the SPIx_MISO, SPIx_D2, and SPIx_D3 signals are also inputs.

• In SPI slave mode, the SPI clock is supplied externally and is called fSPICLKEXT:

• Quad mode is supported by SPI1 and SPI2.

• CPHA is a configuration bit in the SPI_CTL register.

tSPICHS

SPIx_CLK High Period2

2 This specification indicates the minimum instantaneous width or period that can be tolerated due to duty cycle variation or jitter on the external SPIx_CLK. For the external

SPIx_CLK ideal maximum frequency, see the fSPICLKTEXT specification in Table 22.
