4.5.11.6 FLASH and EEPROM Command Register (FCMD)
Only six command codes are recognized in normal user modes as shown in Table 4-15. All other command
codes are illegal and generate an access error. Refer to Section 4.5.3, “Program and Erase Command
Execution,” for a detailed discussion of FLASH and EEPROM programming and erase operations.
