7.2.5.6 Erase Sector Command
The six-cycle Erase Sector command is used to erase a sector in PFLASH or DFLASH.
In PFLASH, either one of the 13 sectors PSx (x = 0-12) or one of the 2 physical sectors
PPS0 or PPS1 that each include four sectors can be erased. In DFLASH, one of its two
banks DB0 or DB1 (identical with sectors DS0 and DS1) can be erased.
The write address transmitted in the last cycle of the Erase Sector command is the sector
start address of the sector PSx that should be erased.
