Figure 34. SPI Interface Timing Diagram Using Motorola MC13180
3.12 SPI Timing Diagrams
To use 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.

The SPI_CLK clock frequency and duty cycle, setup and hold times of receive data can be set by
programming SPI_Control (0x00216138) register together with system clock.
