fixed 32K Flash EEPROM array 11FEE32K. In expanded modes, the
Flash EEPROM arrays are turned off. See
Each 32K byte Flash EEPROM module has a set of registers. The
register space $00F4-$00F7 is in a register space window of four pages.
Each register page of four bytes maps the register space for each Flash
module and each page is selected by the PPAGE register. See
Resource Mapping
LOCK — Lock Register Bit
In normal modes the LOCK bit can only be written once after reset.
This register controls the operation of the Flash EEPROM array.
BOOTP cannot be changed when the LOCK control bit in the
FEELCK register is set or if HVEN or PGM or ERAS in the FEECTL
register is set.
