The SPI module is capable of reaching full-duplex communication speeds up to LSPCLK/4 (where LSPCLK equals SYSCLK). For the maximum rated speed, refer to the device data sheet.
To achieve the maximum full-duplex speeds, the following restrictions are placed on the design:
When configuring the GPIOs to support high-speed mode, refer to Section 27.2.2.1 for more information.
