Load up to one page of data in the column latches from address 0000h to 7FFFh.
Save then disable the interrupts.
Launch the programming by writing the data sequence 50h followed by A0h in
FCON register (only from FM1).
The end of the programming indicated by the FBUSY flag cleared.
Restore the interrupts.
Load data in the column latches from address FF80h to FFFFh.
Save then disable the interrupts.
Launch the programming by writing the data sequence 52h followed by A2h in
FCON register. This step of the procedure must be executed from FM1. The end of
the programming indicated by the FBUSY flag cleared.
The end of the programming indicated by the FBUSY flag cleared.
Restore the interrupts.
The last page address used when loading the column latch is the one used to select the
page programming address.
