  You can not use the Master SPI Mode(MSPI) to access the on-chip Flash memory. This mode is exclusively for SRAM memory configuration. You can use the MSPI port for programming the external SPI Flash device through JTAG mode. This provides a single ...

• 1422 - Can I configure the configuration SRAM memory with the Slave SPI Mode(SSPI)?

  You can not configure the configuration SRAM memory directly with the Slave SPI Mode(SSPI), nor can you read back SRAM memory with the SSPI. But you can use the SSPI to configure the SRAM memory through a REFRESH instruction. The effect is the same ...
