These bits define the programming commands for the flash.

Table 1. NVM Programming commands
Operation Type	NVMCMD		Mnemonic	Description
Operation Type	Binary	Hex	Mnemonic	Description
General	0b000000	0x00	NO_OPERATION	No operation
	0b010000	0x10	CHIP_ERASE	Chip erase⁽¹⁾
	0b010001	0x11	CHIP_WRITE	Write chip⁽²⁾
Section	0b010100	0x14	SECTION_ERASE	Section erase
Word	0b011101	0x1D	WORD_WRITE	Word write
Page	0b011000	0x18	PAGE_ERASE	Erase page

Notes:

1.Erase the Code section and the Non-Volatile Memory lock bits.
2.Write the Code section, but doesn't affect the Non-Volatile Memory lock bits. Self-programming supports NO_OPERATION, WORD_WRITE, and PAGE_ERASE
