tion of the command and status bits available
for EECTRL.
This register is used to initiate either the Flash
Mass Erase cycle or the Flash Page Erase cycle.
See the
Flash Bank Selection.
Flash Page Erase Address register. Contains
the flash memory page address (page 0 through
page 127) that will be erased (default = 0x00).
Must be re-written for each new Page Erase
cycle.
Program Write Enable:
Mass Erase Enable:
Must be re-written for each new Mass Erase cycle.
Protects flash from address CE_LCTN*1024 to
the end of memory from flash page erase.
Protects flash from address 0 to address
BOOT_SIZE*1024 from flash page erase.
Enables security provisions that prevent external
reading of flash memory and CE program RAM.
This bit is reset on chip reset and may only be set.
Attempts to write zero are ignored.
Indicates that the preboot sequence is active.
