RNFULLF is set when more than three 16-bit words or six 8-bit bytes of data remain in
the receive FIFO provided C3[4] = 0 or when more than two 16-bit words or four 8-bit
bytes of data remain in the receive FIFO provided C3[4] = 1.

Clearing this interrupt depends on the state of C3[3] and the status of RNFULLF. Refer
to the description of the SPI status (S) register.

17.5 Initialization/application information

This section discusses an example of how to initialize and use the SPI.

17.5.1 Initialization sequence

Before the SPI module can be used for communication, an initialization procedure must
be carried out, as follows:

1. Update the Control Register 1 (SPIx_C1) to enable the SPI and to control interrupt

enables. This register also sets the SPI as master or slave, determines clock phase and
polarity, and configures the main SPI options.

2. Update the Control Register 2 (SPIx_C2) to enable additional SPI functions such as

the SPI match interrupt feature, the master mode-fault function, and bidirectional
mode output as well as to control 8- or 16-bit mode selection and other optional
features.

3. Update the Baud Rate Register (SPIx_BR) to set the prescaler and bit rate divisor for

an SPI master.

4. Update the Hardware Match Register (SPIx_MH:SPIx_ML) with the value to be

compared to the receive data register for triggering an interrupt if hardware match
interrupts are enabled.

5. In the master, read SPIx_S while S[SPTEF] = 1, and then write to the transmit data

register (SPIx_DH:SPIx_DL) to begin transfer.

17.5.2 Pseudo-Code Example

In this example, the SPI module is set up for master mode with only hardware match
interrupts enabled. The SPI runs in 16-bit mode at a maximum baud rate of bus clock
divided by 2. Clock phase and polarity are set for an active-high SPI clock where the first
edge on SPSCK occurs at the start of the first cycle of a data transfer.
