These bits can only be reset on POR.
All other combinations of NVMOP<3:0> are unimplemented.
Available in ICSP™ mode only; refer to the device programming specification.
WR: Write Control bit
1 = Initiates a Flash memory program or erase operation; the operation is self-timed and the bit is
0 = Program or erase operation is complete and inactive
WREN: Write Enable bit
1 = Enable Flash program/erase operations
0 = Inhibit Flash program/erase operations
WRERR: Write Sequence Error Flag bit
1 = An improper program or erase sequence attempt or termination has occurred (bit is set
0 = The program or erase operation completed normally
Unimplemented: Read as ‘0’
ERASE: Erase/Program Enable bit
1 = Perform the erase operation specified by NVMOP<3:0> on the next WR command
0 = Perform the program operation specified by NVMOP<3:0> on the next WR command
Unimplemented: Read as ‘0’
NVMOP<3:0>: NVM Operation Select bits
1111 = Memory bulk erase operation (ERASE = 1) or no operation (ERASE = 0)
0011 = Memory word program operation (ERASE = 0) or no operation (ERASE = 1)
0010 = Memory page erase operation (ERASE = 1) or no operation (ERASE = 0)
0001 = Memory row program operation (ERASE = 0) or no operation (ERASE = 1)
