Write enable (EWEN) and Write disable (EWDS)
The EWEN instruction puts the S-29XX0A Series into write enable mode, which accepts WRITE, ERASE, WRAL,
and ERAL instructions. The EWDS instruction puts the S-29XX0A Series into write disable mode, which refuses
WRITE, ERASE, WRAL, and ERAL instructions.
The S-29XX0A Series powers on in write disable mode, which protects data against unexpected, erroneous write
operations caused by noise and/or CPU malfunctions. It should be kept in write disable mode except when
performing write operations.
