3.2.6.11
To perform an erase of the data memory, the following
sequence must be performed.
1.
2.
Data memory won’t erase if code-protected (CPD = 0).
FIGURE 3-14:
3.2.6.12
This command erases the 16-word row of program
memory pointed to by PC<11:4>. If the program
memory array is protected (CP = 0) or the PC points to
the configuration memory (>0x2000), the command is
ignored.
To perform a Row Erase Program Memory, the
following sequence must be performed.
