Legend:

S = Settable bit

HC = Hardware Clearable bit

r = Reserved bit

R = Readable bit

W = Writable bit

‘0’ = Bit is cleared

x = Bit is unknown

-n = Value at POR

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

HSC = Hardware Settable/Clearable bit

bit 15

WR: Write Control bit(1)

1 = Initiates a Flash memory program or erase operation; the operation is self-timed and the bit is

cleared by hardware once the operation is complete

0 = Program or erase operation is complete and inactive

bit 14

WREN: Write Enable bit(1)

1 = Enables Flash program/erase operations

0 = Inhibits Flash program/erase operations

bit 13

WRERR: Write Sequence Error Flag bit(1)

1 = An improper program or erase sequence attempt, or termination has occurred (bit is set

automatically on any set attempt of the WR bit)

0 = The program or erase operation completed normally

bit 12

NVMSIDL: NVM Stop in Idle bit

1 = Removes power from the program memory when device enters Idle mode

0 = Powers program memory in Standby mode when the device enters Idle mode

bit 11-10

Reserved: Maintain as ‘0’

bit 9-4

Unimplemented: Read as ‘0’

bit 3-0

NVMOP<3:0>: NVM Operation Select bits(1,2)

1110 = Chip erases user memory (does not erase Device ID, customer OTP or executive memory)

0100 = Unused

0011 = Erases a page of program or executive memory

0010 = Row programming operation

0001 = Double-word programming operation

Note 1:

These bits can only be reset on a Power-on Reset.

All other combinations of NVMOP<3:0> are unimplemented.
