What happens if an interrupt is introduced while sending any portion of the READ command sequence to the SPI FLASH?
If an interrupt is introduced while sending any part of the READ command to the SPI FLASH, the SPI FLASH itself will terminate the command sequence. Therefore, once the interrupt is completed, it is necessary to re-initiate the entire READ command to also include the 24-bit address. The entire READ command and 24-bit address command sequence cannot be interrupted. Product Marketing suggests disabling all interrupts to prevent re-initiating the entire READ & 24-bit address command sequence.
