This method reads the specified number of bytes, starting at the given address given, and writes them into the blob passed as the method’s second parameter. The bytes will be written at the current location of the blob’s read/write pointer, which can be determined with the blob.tell() method and set with the blob.seek() method.
Contrast this method with spiflash.read(), which performs the same task but returns the bytes read from the SPI flash as a new blob object.
