3.14. SPI Interfaces
The module provides two SPI interfaces supporting only master mode. The maximum clock frequency of
SPI is up to 50 MHz.
Table 20: Pin Definition of SPI Interfaces
The following figure shows the timing relationship of SPI interfaces. The related parameters of SPI timing
are shown in the table below.
