Table 25 SPI Master Signal Names
The main purpose of the SPI Master block is to transfer data between an external SPI interface and the
VNC2. It does this under the control of the CPU and DMA engine via the on chip I/O bus.
An SPI master interface transfer can only be initiated by the SPI Master and begins with the slave select
signal being asserted. This is followed by a data byte being clocked out with the master supplying SCLK.
The master always supplies the first byte, which is called a command byte. After this the desired number
of data bytes are transferred before the transaction is terminated by the master de-asserting slave
select.
The SPI Master will transmit on MOSI as well as receive on MISO during every data stage. At the end of
each byte spi_tx_done and spi_rx_full_int are set. Figure 6-21 Typical SPI Master Timing and
Table 26 SPI Master Timing show an example of this.
