Atmel 49F001T/002T Operation Notes

These chips all have a boot block with lockout feature. This feature works in a OTP(one-time-program) way, whcih means once it had been activated, it can't be unlocked again. To prevent from accidently enabled, the user must set the Protect-Setting-Byte(PSB) to value 5A(HEX) to let the programmer enable this lockout feature automatically in the COPY command.
