Hello Victor,

Various feature bits are defined as macros in include/flash.h , some of them have comments explaining what they do. If the feature name is not descriptive, and there is no comment, but you think you might need this feature: feel free to ask. I would try to add comments later.

SPI_DISABLE_BLOCKPROTECT_BP4_SRWD and other unlock functions as in spi25_statusreg.c. Those functions have comments, hopefully this can help!

Thanks, Peter,

Where can I find the definition of terms like,

.feature_bits     = FEATURE_WRSR_WREN | FEATURE_OTP | FEATURE_WRSR_EXT2,
SPI_DISABLE_BLOCKPROTECT_BP4_SRWD

Regards,

Victor
