Figure 55. Subsector Erase instruction sequence DIO-SPI
Sector Erase (SE)
The Sector Erase (SE) instruction sets to '1' (FFh) all bits inside the chosen sector. Before it
can be accepted, a Write Enable (WREN) instruction must previously have been executed.
Apart form parallelizing the instruction code and the address on the two pins DQ0 and DQ1,
the instruction functionality is the same as the Sector Erase (SE) instruction of the Extended
SPI protocol, please refer to
Figure 56. Sector Erase instruction sequence DIO-SPI
Bulk Erase (BE)
The Bulk Erase (BE) instruction sets all bits to '1' (FFh). Before it can be accepted, a Write
Enable (WREN) instruction must previously have been executed.
Apart form the parallelizing of the instruction code on the two pins DQ0 and DQ1, the
instruction functionality is exactly the same as the Bulk Erase (BE) instruction of the
Extended SPI protocol, please refer to
