Function

Modifying INFOA addresses when LOCKA = 1 will modify main flash memory

Description

When attempting to write to an address location or perform a segment erase of INFOA while the LOCKA bit is set, flash memory beginning at main memory location 0xFC40 and extending for 64 bytes to address 0xFC7F will be modified erroneously. These 64 bytes are addressed and modified in place of the INFOA addresses when writes or erases are performed within the INFOA address space and LOCKA = 1.

Workaround

Prior to modifying (writing or erasing) any address within the INFOA Flash memory segment, properly clear the LOCKA control bit as described in the MSP430x2xx User's Guide (SLAU144) to unlock the segment. Once the modification is complete, setting the LOCKA bit is recommended.
