PAGEN: Page Number
Note:
Depending on the command, all the possible unused bits of PAGEN are meaningless.
KEY: Write Protection Key
This field should be written with the value 0x5A to enable the command defined by the bits of the register. If the field is writ-
ten with a different value, the write is not performed and no action is started.
