3.9 SPI Timing Diagrams
To utilize the internal transmit (TX) and receive (RX) data FIFOs when the SPI 1 module is configured as
a master, two control signals are used for data transfer rate control: the SS signal (output) and the
SPI_RDY signal (input). The SPI 1 Sample Period Control Register (PERIODREG1) and the SPI 2
Sample Period Control Register (PERIODREG2) can also be programmed to a fixed data transfer rate for
either SPI 1 or SPI 2. When the SPI 1 module is configured as a slave, the user can configure the SPI 1
Control Register (CONTROLREG1) to match the external SPI master’s timing. In this configuration, SS
becomes an input signal, and is used to latch data into or load data out to the internal data shift registers, as
well as to increment the data FIFO. Figure 31 through Figure 35 show the timing relationship of the master
SPI using different triggering mechanisms.
