  When the NVCM of an iCE40 device has already been programmed, it can no longer be configured in Master SPI mode (SPI serial Flash PROM). However, Slave SPI is still possible which could be an external device, such as a processor, microcontroller, or ...

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

  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 ...
