6.4 Serial Peripheral Interface – SPI Master
Figure 6-20 SPI Master block diagram
The SPI Master interface is used to interface to applications such as SD Cards. The SPI Master provides
the following features:
The SPI Master only clocks in and out data that the VNC2 CPU sets up in its register space. The VNC2
CPU interprets the data words that are to be sent and received.
6.4.1 SPI Master Signal Descriptions.
Table 25 shows the SPI master signals and the available pins that they can be mapped to depending on
the package size. Further details on the configuration of input and output signals are available in Section
5 - I/O Multiplexer.
