3.2.3 Row Erase Program Memory

The Row Erase Program Memory command will erase an individual row. If the program memory is code-protected, the Row Erase Program Memory command will be ignored. When the address is 8000h-8004h, the Row Erase Program Memory command will only erase the User ID locations regardless of the setting of the CP Configuration bit. When write and erase operations are done on a row basis, the row size (number of 14-bit words) for erase operation is 32 and the row size (number of 14-bit latches) for the write operation is 32.

The Flash memory row defined by the current PC will be erased. The user must wait TERAR for erasing to complete (see Figure 3-8).
