Can a READ be initiated while in the middle in writing commands to the PNOR FLASH?
In the middle of entering any bus command cycles, you may read data from the FLASH memory array. However, your command cycles already written to the FLASH (program or erase) are now disrupted. It will be required to re-write the bus command cycles to the FLASH without any interruption. It is suggested that a READ operation be performed before writing any bus command cycles to the FLASH. As well, the time period to write each bus command cycle is infinite, as long as constant power is applied and not disrupted. As an example, you may write the first two or three bus command cycles, and wait for the next day to write the remaining bus command cycles. The FLASH should execute the command (program or erase), if no interruptions occurred.
